[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.

DebugInfo: Fix overwriting/loss of inlined arguments to recursively inlined functions.
Due to an unnecessary special case, inlined arguments that happened to
be from the same function as they were inlined into were misclassified
as non-inline arguments and would overwrite the non-inlined arguments.
Assert that we never overwrite a function's arguments, and stop
misclassifying inlined arguments as non-inline arguments to fix this
issue.
Excuse the rather crappy test case - handcrafted IR might do better, or
someone who understands better how to tickle the inliner to create a
recursive inlining situation like this (though it may also be necessary
to tickle the variable in a particular way to cause it to be recorded in
the MMI side table and go down this particular path for location

[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.

Change the { } expression in tablegen to accept sized binary literals which are not just 0 and 1.
It also allows nested { } expressions, as now that they are sized, we can merge pull bits from the nested value.
In the current behaviour, everything in { } must have been convertible to a single bit.
However, now that binary literals are sized, its useful to be able to initialize a range of bits.
So, for example, its now possible to do
bits<8> x = { 0, 1, { 0b1001 }, 0, 0b0 }

Change BitsInit to inherit from TypedInit.
This is useful in a later patch where binary literals such as 0b000 will become BitsInit values instead of IntInit values.

Change TableGen so that binary literals such as 0b001 are now sized.
Instead of these becoming an integer literal internally, they now become bits<n> values.
Prior to this change, 0b001 was 1 bit long. This is confusing as clearly the user gave 3 bits.
This new type holds both the literal value and the size, and so can ensure sizes match on initializers.
For example, this used to be legal
bits<1> x = 0b00;
but now it must be written as
bits<2> x = 0b00;

TableGen: Change { } to only accept bits<n> entries when n == 1.
Prior to this change, it was legal to do something like
bits<2> opc = { 0, 1 };
bits<2> opc2 = { 1, 0 };
bits<2> a = { opc, opc2 };
This involved silently dropping bits from opc and opc2 which is very hard to debug.
Now the above test would be an error. Having tested with an assert, none of LLVM/clang was relying on this behaviour.
Thanks to Adam Nemet for the above test.
