This patch adds instruction latencies for the SSE instructions
to the instruction scheduler for the Intel Atom.

Duncan pointed out that if the alignment isn't explicitly specified, it defaults to the ABI alignment.  Given that, make this code a bit more aggressive in such cases.

First clear def map of Q1, etc.

We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

Teach BasicAA about the LLVM IR rules that allow reading past the end of an object given sufficient alignment.  Fixes PR12098.

After the SlotIndex slot names were updated, it is possible to apply
stricter checks to live intervals.

Also treat bundles as bags of operands when checking live intervals.

thumb instruction.  The PC adjustment is +4 in Thumb mode and +8 in ARM mode.

The MIOperands iterator can visit operands on a single instruction, or
all operands in a bundle.  This simplifies code like the register
allocator that treats bundles as a set of operands.

value numbers to be assigned when calculating any particular value number.
Enhance the logic that detects new value numbers to take this into account,
for a tiny compile time speedup.  Fix a comment typo while there.

%cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and
with "false" under the false edge.  This change enhances this to replace the
negated compare (A!=B) with "false" under the true edge and "true" under the
false edge.  Reported to improve perlbench results by 1%.
