Nadav Rotem e649d66552 Fix pr11193. 
SHL inserts zeros from the right, thus even when the original
sign_extend_inreg value was of 1-bit, we need to sra.

Bill Wendling 94e6643fce The different flavors of ARM have different valid subsets of registers. Check 
that the set of callee-saved registers is correct for the specific platform.

Jim Grosbach 2f2e3c4737 ARM VLD parsing and encoding. 
Next step in the ongoing saga of NEON load/store assmebly parsing. Handle
VLD1 instructions that take a two-register register list.

Adjust the instruction definitions to only have the single encoded register
as an operand. The super-register from the pseudo is kept as an implicit def,
so passes which come after pseudo-expansion still know that the instruction
defines the other subregs.

Owen Anderson 03a173eb71 Don't automatically set the "fc" bits on MSR instructions if the user didn't ask for them. This is a divergence from gas' behavior, but it is correct per the documentation and allows us to forge ahead with roundtrip testing.

Lang Hames aaf379027d Haven't yet found a nice way to handle TargetData verification in the 
AsmParser. This patch adds validation for target data layout strings upon
construction of TargetData objects. An attempt to construct a TargetData object
from a malformed string will trigger an assertion.

James Molloy 2d768fd379 Use literal pool loads instead of MOVW/MOVT for materializing global addresses when optimizing for size. 
On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is
codesize including literal pools.

The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there
is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries.

Fixes PR11087.

Bill Wendling 4969dcdef9 Use the integer compare when the value is small enough. Use the "move into a

move the value into the register in the "movw, movt" pair of instructions.

Bill Wendling 617075fcf6 A landing pad could have more than one predecessor. In that case, we want that 
predecessor to remove the jump to it as well. Delay clearing the 'landing pad'
flag until after the jumps have been removed. (There is an implicit assumption
in several modules that an MBB which jumps to a landing pad has only two
successors.)
