f4e8af6ecc StringRef: Add find(char) and find(StringRef). 
Also, regroup functions.

30d9c39337 pass the TargetTriple down from each target ctor to the 
LLVMTargetMachine ctor.  It is currently unused.

40af6d5199 now that JumpTableDirective can differentate picness itself, MIPS TAI 
no longer needs a targetmachine to initialize itself.

45bdc96988 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC 
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.

0cb77e23a9 "TAI::JumpTableDirective" is always null for current arm targets, simplify 
the code based on this and make it fall through better.

490f80eb1c Simplify ConstantExpr::getInBoundsGetElementPtr and fix a possible crash, if 
constant folding eliminated the GEP instruction.
 - clang was hitting this on its test suite (for x86_64, at least).

434a66fa9b Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to 
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.
