082043aa74 projects: Don't try to build libcxx if one happens to have it checked out into 
llvm/projects.

8849104392 Add an elf-dumper utility. 
- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.

4a66e8e24d Get rid of the last use of -m64 in FrontendC. This solution 
of checking for either 4 or 8 is not very satisfactory, but
it would catch the original problem (an alignment of 1).

3030644248 Another test that uses -m64. Here too it looks like it can be 
removed.  Not that the XTARGET wasn't doing anything since it
does nothing without an accompanying XFAIL.

e89d619d23 On i386, llvm-gcc cannot be assumed to support -m64. Since these 
tests pass here (i686-linux and x86-64-linux) without -m64, simply
remove the -m64.

524123343c Fix NEON VLD pseudo instruction itineraries that were incorrectly copied from 
the VST pseudos.  The VLD/VST scheduling still needs work (see pr6722), but
at least we shouldn't confuse the loads with the stores.

2b284b178f For double-spaced VLD3/VLD4 instructions, copy the explicit super-register use 
operand from the pseudo instruction to the new instruction as an implicit use.
This will preserve any other flags (e.g., kill) on the operand.

92b5646145 Simplify copying over operands from pseudo NEON load/store instructions. 
For VLD3/VLD4 with double-spaced registers, add the implicit use of the
super register for both the instruction loading the even registers and the
instruction loading the odd registers.

956afdd1f2 Relax the "don't unroll loops containing calls" rule. Instead, when a loop contains a call, lower the 
unrolling threshold to the optimize-for-size threshold.  Basically, for loops containing calls, unrolling
can still be profitable as long as the loop is REALLY small.

464762ad1a Add intrinsic forms of mmx<->sse conversions. Notes: 
Omission of memory form of PI2PD is intentional; this
does not use an MMX register and does not put the chip
into MMX mode (PI2PS, oddly enough, does).
Operands of PI2PS follow the gcc builtin, not Intel.

a83eb43cb8 A script that tests a certain release candidate in several modes. It does a 
2-phase build of llvm and llvm-gcc, similar to what the buildbots do, and runs
the regression testsuite.

Things to do:

- Work out some bugs with llvm-gcc flags.
- Not all platforms support ObjC.
- Run the test-suite.

892c337123 x86 vector shuffle lowering now relies only on target specific 
nodes to emit shuffles and don't do isel mask matching anymore.
- Add the selection of the remaining shuffle opcode (movddup)
- Introduce two new functions to "recognize" where we may get
potential folds and add several comments to them explaining why
they are not yet in the desidered shape.
- Add more patterns to fallback the case where we select
a specific shuffle opcode as if it could fold a load, but it
can't, so remap to a valid instruction.
- Add a couple of FIXMEs to address in the following days once
there's a good solution to the current folding problem.
