a54934ae9d add some accessors to callsite/callinst/invokeinst to check
for the noinline attribute, and make the inliner refuse to
inline a call site when the call site is marked noinline even
if the callee isn't.  This fixes PR6682.

f65b0e9b45 XFAIL tests from LLVMC on valgrind or valgrind+leak-checking. We
don't care about leaks from tblgen, and I assume we don't care about
valgrind errors in llvm-gcc/g++.

32989deb96 Add support for XFAILing valgrind runs with memory leak checking independently
of runs without leak checking.  We add -vg to the triple for non-checked runs,
or -vg_leak for checked runs.  Also use this to XFAIL the TableGen tests, since
tablegen leaks like a sieve.  This includes some valgrindArgs refactoring.

b46b03b36f Fixed the encoding problems of the crc32 instructions. All had the Operand size
override prefix and only the r/m16 forms should have had that.  Also for variant
one, the AT&T syntax, added suffixes to all forms.  Also added the missing
64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.

602b40f0d0 MC/Mach-O/x86_64: Add relocation support.
- This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
 - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
 - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)

1ff781fb50 Work around a valgrind oddity where it doesn't pass the full path of a
script to the #! command by using bash instead of /bin/sh.  Bash
searches $PATH for its script argument, but dash, which /bin/sh
resolves to on some systems, does not.

d30a98e43a Initial ARM/Thumb disassembler check-in. It consists of a tablgen backend

999aee24c7 Fix the third (and last known) case of code update problems due
to LLVM IR changes with addr label weirdness.  In the testcase, we
generate references to the two bb's when codegen'ing the first
function:

_test1:                                 ## @test1
	leaq	Ltmp0(%rip), %rax
..
	leaq	Ltmp1(%rip), %rax

Then continue to codegen the second function where the blocks
get merged.  We're now smart enough to emit both labels, producing
this code:

_test_fun:                              ## @test_fun
## BB#0:                                ## %entry
Ltmp1:                                  ## Block address taken
Ltmp0:
## BB#1:                                ## %ret
	movl	$-1, %eax
	ret

Rejoice.

4e815f8a8c MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.
