Summary:
TestInlineStepping tests LLDB's ability to step in the presence of
inline frames. The testcase source has a number of functions and some
of them are marked `always_inline`.
The test is built around the assumption that the inline function will
be fully represented once inlined, but this is not true with the
current arm64 code generation. For example:
void caller() {
always_inline_function(); // Step here
}
When stppeing into `caller()` above, you might immediatly end up in
the inlines frame for `always_inline_function()`, because there might
literally be no code associated with `caller()` itself.
This patch hacks around the issue by adding an `asm volatile("nop")`
on some lines with inlined calls where we expect to be able to
step. Like so:
void caller() {
asm volatile("nop"); always_inline_function(); // Step here
}
This guarantees there is always going to be one instruction for this
line in the caller.

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.
