ARM: correct isPredicable for MULS in ThHUMB mode
The ARM ARM states that CPSR may not be updated by a MUL in thumb mode. Due to
an ordering of Thumb 2 Size Reduction and If Conversion, we would end up
generating a THUMB MULS inside an IT block.
The If Conversion pass uses the TTI isPredicable method to ensure that it can
transform a Basic Block. However, because we only check for IT handling on
Thumb2 functions, we may miss some cases. Even then, it only validates that the
CPSR is not *live* rather than it is not accessed. This corrects the handling
for that particular case since the same restriction does not hold on the vast
majority of the instructions.
This does prevent the IfConversion optimization from kicking in in certain
cases, but generating correct code is more valuable. Addresses PR20555.

[AArch64] Add an FP load balancing pass for Cortex-A57
For best-case performance on Cortex-A57, we should try to use a balanced mix of odd and even D-registers when performing a critical sequence of independent, non-quadword FP/ASIMD floating-point multiply or multiply-accumulate operations.
This pass attempts to detect situations where the register allocation may adversely affect this load balancing and to change the registers used so as to better utilize the CPU.
Ideally we'd just take each multiply or multiply-accumulate in turn and allocate it alternating even or odd registers. However, multiply-accumulates are most efficiently performed in the same functional unit as their accumulation operand. Therefore this pass tries to find maximal sequences ("Chains") of multiply-accumulates linked via their accumulation operand, and assign them all the same "color" (oddness/evenness).
This optimization affects S-register and D-register floating point multiplies and FMADD/FMAs, as well as vector (floating point only) muls and FMADD/FMA. Q register instructions (and 128-bit vector instructions) are not affected.

[AVX512] Generate masking instruction variants with tablegen
After adding the masking variants to several instructions, I have decided to
experiment with generating these from the non-masking/unconditional
variant. This will hopefully reduce the amount repetition that we currently
have in order to define an instruction with all its variants (for a reg/mem
instruction this would be 6 instruction defs and 2 Pat<> for the intrinsic).
The patch is the first cut that is currently only applied to valignd/q to make
the patch small.
A few notes on the approach:
* In order to stitch together the dag for both the conditional and the
unconditional patterns I pass the RHS of the set rather than the full
pattern (set dest, RHS).
* Rather than subclassing each instruction base class (e.g. AVX512AIi8),
with a masking variant which wouldn't scale, I derived the masking
instructions from a new base class AVX512 (this is just I<> with
Requires<HasAVX512>). The instructions derive from this now, plus a new set
of classes that add the format bits and everything else that instruction
base class provided (i.e. AVX512AIi8 vs. AVX512AIi8Base).
I hope we can go incrementally from here. I expect that:
* We will need different variants of the masking class. One example is
instructions requiring three vector sources. In this case we tie one of the
source operands to dest rather than a new implicit source operand ($src0)
* Add the zero-masking variant
* Add more AVX512*Base classes as new uses are added
I've looked at X86.td.expanded before and after to make sure that nothing got
lost for valignd/q.
