These tests fail on FreeBSD due to missing build support, the same reason
they fail on Linux.

This patch implements parsing of mips FCC register operands. The example instructions have been added to test files.

It needs interface that is missing from the NDK, and it is not used on Android anyway.

clang/test/Driver/qa_override.c: Resurrect a part of r187376. It still requires the feature 'clang-driver' for cygming.

When simplifying a (or (and B A) (and C ~A)) to a (VBSL A B C) ensure that the
bitwidth of the second operands to both ands match before comparing the negation
of the values.

Split the check of the value of the second operands to the ands.  Move the cast
and variable declaration slightly higher to make it slightly easier to follow.

Added the notion of Type and TargetSpecific attributes to the clang tablegen.  In turn, this fixes a mistake with Ptr32, Ptr64, UPtr and SPtr attribtues generating AST nodes that are never actually used.

This is the first of many upcoming patches for PowerPC fast
instruction selection support.  This patch implements the minimum
necessary for a functional (but extremely limited) FastISel pass.  It
allows the table-generated portions of the selector to be created and
used, but in most cases selection will fall back to the DAG selector.
None of the block terminator instructions are implemented yet, and
most interesting instructions require some special handling.
Therefore there aren't any new test cases with this patch.  There will
be quite a few tests coming with future patches.

This patch adds the make/CMake support for the new code (including
tablegen -gen-fast-isel) and creates the FastISel object for PPC64 ELF
only.  It instantiates the necessary virtual functions
(TargetSelectInstruction, TargetMaterializeConstant,
TargetMaterializeAlloca, tryToFoldLoadIntoMI, and FastLowerArguments),
but of these, only TargetMaterializeConstant contains any useful
implementation.  This is present since the table-generated code
requires the ability to materialize integer constants for some
instructions.

This patch has been tested by building and running the
projects/test-suite code with -O0.  All tests passed with the
exception of a couple of long-running tests that time out using -O0
code generation.

Refactor some attributes to use checkFunctionOrMethodArgumentIndex instead of using custom logic.  No functional changes intended.

build_vector is lowered to REG_SEQUENCE, which is something the register
allocator does a good job at optimizing.

llvm-svn: 187397

This patch prevents the following combine when the input vector is used more
than once.
insert_vector_elt (build_vector elt0, ..., eltN), NewEltIdx, idx
=>
build_vector elt0, ..., NewEltIdx, ..., eltN 

The reasons are:
- Building a vector may be expensive, so try to reuse the existing part of a
  vector instead of creating a new one (think big vectors).
- elt0 to eltN now have two users instead of one. This may prevent some other
  optimizations.

Fixed a crasher when using memory threads where a thread is sticking around too long and was causing problems when it didn't have a thread plan.

The problem is due to the section name being explicitly mentioned in
the IR and differing between the two platforms.

update testcase to make sure we generate debug info for walrus
by adding a non-trivial constructor and verify that we don't
emit an ODR signature for the type.

The command line option in .drectve section may be quoted by double
quotes, and if that's the case we have to remove them.

- newer gcc generates additional debuginfo for function exit (stack object desctruction) which was causing tests to fail
- work-around consists of not declaring any stack objects in main()

This patch removes hacky mangle() function, which strips all decorations
uncondtitionally. LLD now interprets Import Name/Type field in the import
library properly as described in the Microsoft PE/COFF Spec.
