Sean Callanan c530ba98a9 Import block pointers from DWARF as Clang block pointers, not as structs.
Also added a data formatter that presents them as structs if you use frame
variable to look at their contents.  Now the blocks testcase works.

Greg Clayton d49a8f9b54 Watch out for compilers that generate bad bitfield info. If the bit size of a bitfield member doesn't lie within the bit bounds of the type itself, just leave it out so we don't get clang asserting and killing our IDE when it gets unhappy with the information.

Sean Callanan 7736a208b8 [fix] Fixed a bug where const this would cause parser errors about $__lldb_expr.
In templated const functions, trying to run an expression would produce the
error

error: out-of-line definition of '$__lldb_expr' does not match any declaration
in 'foo' member declaration does not match because it is const qualified
error: 1 error parsing expression

which is no good.  It turned out we don't actually need to worry about "const,"
we just need to be consistent about the declaration of the expression and the
FunctionDecl we inject into the class for "this."

Also added a test case.

Greg Clayton cae0855a62 DWARF layout for bitfields is wrong when the bit offset is negative.
Some older versions of clang emitted bit offsets that were negative and these bitfields would have their bitfield-ness stripped off and it would cause a clang assertion in clang assertions were enabled. I updated the bitfield C test to make sure we don't regress.

Ulrich Weigand 7e8de59b90 Fix test cases for big-endian systems
A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.

These two test cases:
  tools/lldb-server/lldbgdbserverutils.py
  python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.

These test cases:
  functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
  functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
  functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
  lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
  python_api/sbdata/TestSBData.py  (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly.  For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.

These test case:
  python_api/sbdata/TestSBData.py  (second change)
  functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.

Todd Fiala 58c4dd7a71 make TestRegisterVariables slightly more resilient
This test sets the compiler optimization level to -O1 and
makes some assumptions about how local frame vars will be
stored (i.e. in registers).  These assumptions are not always
true.

I did a first-pass set of improvements that:
(1) no longer assumes that every one of the target locations has
    every variable in a register.  Sometimes the compiler
    is even smarter and skips the register entirely.
(2) simply expects one of the 5 or so variables it checks
    to be in a register.

This test probably passes on a whole lot more systems than it
used to now.  This is certainly true on OS X.

Adrian Prantl 6aeba89e89 Support floating point values in 128-bit SSE vector registers
The System-V x86_64 ABI requires floating point values to be passed
in 128-but SSE vector registers (xmm0, ...). When printing such a
variable this currently yields an <invalid load address>.

This patch makes LLDB's DWARF expression evaluator accept 128-bit
registers as scalars. It also relaxes the check that the size of the
result of the DWARF expression be equal to the size of the variable to a
greater-than. DWARF defers to the ABI how smaller values are being placed
in a larger register.

Implementation note: I found the code in Value::SetContext() that changes
the m_value_type after the fact to be questionable. I added a sanity check
that the Value's memory buffer has indeed been written to (this is
necessary, because we may have a scalar value in a vector register), but
really I feel like this is the wrong place to be setting it.

Adrian McCarthy 536183275d Fix TestInlines.py on Windows
The inlining semantics for C and C++ are different, which affects the test's expectation of the number of times the function should appear in the binary.  In the case of this test, C semantics means there should be three instances of inner_inline, while C++ semantics means there should be only two.

On Windows, clang uses C++ inline semantics even for C code, and there doesn't seem to be a combination of compiler flags to avoid this.

So, for consistency, I've recast the test to use C++ everywhere.  Since the test resided under lang/c, it seemed appropriate to move it to lang/cpp.

This does not address the other XFAIL for this test on Linux/gcc.  See https://llvm.org/bugs/show_bug.cgi?id=26710

expectedFailureWindows is equivalent to using the general

by moving towards these common decorators we can solve the issue
of having to support decorators that can be called with or without

and this is enforced by design (because you can't specify the condition
you're decorating for without passing an argument) the implementation
of the decorators can become much simpler
