ff233c9e5c Change the representation of MCCFIInstruction. 
We now store the Register and Offset directly. MachineLocation is gone (from
this file)!

7f74d2c2c1 Give each MCCFIInstruction its own opcode. 
This untangles the switch cases of the old Move and RelMove opcodes a bit
and makes it clear how to add new instructions.

28c9ea3c13 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.

4ccb49a838 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.

985884caf9 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.

72a2c0622a 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!

198ad916d7 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.

07df765e65 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.
