Make category-specifying files visible. There is really no good reason
to keep them hidden, and having them visible increases the chances
that someone will actually spot them.

Replace the plethora of ObjC-implied 'skipUnlessDarwin' decorators
with marking tests as 'objc' category (whenever missing), and skip all
ObjC tests on non-Darwin platforms. I have used '.categories' file
wherever it was present already or all (>1) tests were relying on ObjC,
and explicit add_test_categories() where there was only one test.

Add preconditions to `TestBase.expect()` that catch semantically invalid calls
that happen to succeed anyway. This also fixes the broken callsites caught by
these checks.
This prevents the following incorrect calls:
1. `self.expect("lldb command", "some substr")`
2. `self.expect("lldb command", "assert message", "some substr")`

Summary:
Certain `NSDate` constructors return a special `NSConstantDate` class which
currently ends up being unformatted as it's not in the list of supported classes
for the NSDate formatter. This patch adds that class to the supported class list
so LLDB produces a summary for it.
One of these special constructors is `[NSDate distantPast]` which returns the
date for `0001-01-01 00:00:00 UTC`. LLDB has a special case for formatting this
date but for some reason we did hardcode the wrong summary string in that
special case. Maybe the summary string was correct back when the code was
written but it isn't correct anymore (`distantPast` isn't actually defined to be
a special date but just some 'a guaranteed temporal boundary.' so maybe someone
changed the value in the last 10 years).
If someone else is wondering why we even have this special case for
`distantPast` but not for the future. The reason seems to be that our date
formatting for really old dates is off by 24 hours. So for example, adding one
second to `distantPast` will cause LLDB to print `0000-12-30 00:00:01 UTC`
(which is 24 hours behind the expected result). So to make our code appear to be
correct it seems we just hardcoded the most common NSDate result from that time
span. I'll replace that logic with a generic solution in a probably more
invasive follow up patch.
I also took the freedom to replace the magic value `-63114076800` with some
constant + documentation. I heard there are some people that don't know from the
top of their head that there are 63114076800 seconds between 1. Jan 0001 and 1.
January 2001 in whatever calendar system NSDate is using.

Summary:
When printing an NSDate (for example with `NSLog` or `po`) the seconds value is
always rounded down. LLDB's own formatter however isn't following that behaviour
which leads to situations where the formatted result is sometimes one second
off. For example:
```
(lldb) p [NSDate dateWithTimeIntervalSince1970:0.1]
(__NSTaggedDate *) $1 = [...] 1970-01-01 00:00:01 UTC
(lldb) po [NSDate dateWithTimeIntervalSince1970:0.1]
1970-01-01 00:00:00 +0000
(lldb) p [NSDate dateWithTimeIntervalSince1970:0.6]
(__NSTaggedDate *) $4 =[...] 1970-01-01 00:00:01 UTC
(lldb) po [NSDate dateWithTimeIntervalSince1970:0.6]
1970-01-01 00:00:00 +0000
```
This patch just always rounds down the seconds value we get from the NSDate
object.

This patch improves data formatting for CFDictionaryRef and CFSetRef.
It uses the same data-formatter as NSCFDictionaries and NSCFSets introduced
previously but did require some adjustments in Core::ValueObject.
Since the "Ref" types are opaque pointers to the actual CF containers, if the
value object has a synthetic value, lldb will use the opaque pointer's pointee
type to create the new ValueObjectChild needed to dereference the ValueObject.
This allows the "Ref" types to behaves the same as CF containers when used with
the `frame variable` command, the SBAPI or in Xcode's variable inspector.
This patch also adds support for incomplete types in ValueObject.

The source file used to test Objective-C data-formatters didn't respected
any formatting (mixed tab and spaces, lines exceed column 80, etc...).
This patch reformats the file using clang-format to make it easier to

This patch improves data formatting for CoreFoundation containers:
CFDictionary and CFSet.
These data formatters make the containers and their children appear in Xcode's
variables view (and on the command line) without having to expand the
data structure.
Previous implementation only supported showing the container's element count.
```
(lldb) frame var dict
(__NSCFDictionary *) dict = 0x00000001004062b0 2 key/value pairs
(lldb) frame var set
(__NSCFSet *) set = 0x0000000100406330 2 elements
```
Now the variable can be dereferenced to dispaly the container's children:
```
(lldb) frame var *dict
(__NSCFDictionary) *dict = {
[0] = {
key = 0x0000000100004050 @"123"
value = 0x0000000100004090 @"456"
}
[1] = {
key = 0x0000000100004030 @"abc"
value = 0x0000000100004070 @"def"
}
}
(lldb) frame var *set
(__NSCFSet) *set = {
[0] = 0x0000000100004050 @"123"
[1] = 0x0000000100004030 @"abc"
}
```

(This is D68010 but I also set the new parameter in LibStdcpp.cpp to fix
the Debian tests).
Summary:
Printing a summary for an empty NSPathStore2 string currently prints random bytes behind the empty string pointer from memory (rdar://55575888).
It seems the reason for this is that the SourceSize parameter in the `ReadStringAndDumpToStreamOptions` - which is supposed to contain the string
length - actually uses the length 0 as a magic value for saying "read as much as possible from the buffer" which is clearly wrong for empty strings.
This patch adds another flag that indicates if we have know the string length or not and makes this behaviour dependent on that (which seemingly
was the original purpose of this magic value).

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:
lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
lldb-shell :: Reproducer/TestGDBRemoteRepro.test

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
