Rafael Espindola 1c3086cc91 Refactor how MCCFIInstructions are created. 
Give MCCFIInstruction a single, private constructor and add helper static
methods that create each type of cfi instruction. This is is preparation
for changing its representation. The representation with a pair
MachineLocations older than MC and has been abused quiet a bit to support
more cfi instructions.

Benjamin Kramer 455fa35e51 CodeGenPrepare: Move ret duplication out of the instruction iteration loop. 
It can delete the block, and the loop continues on free'd memory.
No change in output. Found by valgrind.

Rafael Espindola b3b60570e3 Add a -disable-cfi option to llvm-mc. This is useful for debugging as 
it will expand any .cfi_* directives in the input assembly.

Unfortunately this cannot replace elf-dump in tests as the asm streamer
cannot relax the line advance opcodes.

Meador Inge 780a1861f1 Add more functions to the target library information. 
I discovered a few more missing functions while migrating optimizations
from the simplify-libcalls pass to the instcombine (I already added some
in r167659).

Preston Briggs 3ad394931d Corrects a problem where we reply exclusively of GEPs to drive 
analysis.  Better is to look for cases with useful GEPs and use them
when possible.  When a pair of useful GEPs is not available, use the
raw SCEVs directly. This approach supports better analysis of pointer
dereferencing.

In parallel, all the test cases are updated appropriately.
Cases where we have a store to *B++ can now be analyzed!

Jack Carter b05cb67b81 Mips direct object xgot support 
This patch provides support for the MIPS relocations:

    *)  R_MIPS_GOT_HI16
    *)  R_MIPS_GOT_LO16
    *)  R_MIPS_CALL_HI16
    *)  R_MIPS_CALL_LO16

These are used for large GOT instruction sequences.

Rafael Espindola ff571cce2f Using "not grep" is brittle as the test passes if llvm-as fails.

Chandler Carruth 845b73c06f PR14055: Implement support for sub-vector operations in SROA. 
Now if we can transform an alloca into a single vector value, but it has
subvector, non-element accesses, we form the appropriate shufflevectors
to allow SROA to proceed. This fixes PR14055 which pointed out a very
common pattern that SROA couldn't handle -- mixed vec3 and vec4
operations on a single alloca.
