This patch includes MC layer support for VOP3 encoded instructions and generic VOP support
classes.
Some VOP1 and VOP2 instructions which share an encoding with gfx10 and are using
the AssemblerPredicate = isGFX10Plus are also enabled. That predicate
will be changed to isGFX10Only in a later patch.

We always had global and scratch loads to LDS in the gfx9,
but did not handle it. These were available via the 'lds'
encoding bit. In gfx940 this bit was reused as 'svs' which
resulted in new '_lds' opcodes effectively pushing this
bit into the opcode, but functionally it is the same. These
instructions are also available on gfx10.

The original design of custom operands support assumed that most GPUs
have the same or very similar operand names end encodings. This is
no longer the case. As a result the support code becomes over-complicated
and difficult to maintain.
This change implements a different design with the following benefits:
- support of aliases;
- support of operands with overlapped encodings;
- identification of defined but unsupported operands.

The namespaces of HWREGs is now overlapping with gfx10. Thus the
patch is longer than necessary to just support new names. It also
need to handle proper error messages, i.e. to issue a "specified
hardware register is not supported on this GPU" message.
This may need a major refactoring in the future.

gfx90a allows the number of ACC registers (AGPRs) to be set
independently to the VGPR registers. For both HSA and PAL metadata, we
now include an "agpr_count" key to report the number of AGPRs set for
supported devices (gfx90a, gfx908, as determined by hasMAIInsts()).
This is collected from SIProgramInfo.NumAccVGPR for both HSA and PAL.
The AsmParser also now recognizes ".kernel.agpr_count" for supported
devices.

As usual with that header cleanup series, some implicit dependencies now need to
be explicit:
llvm/MC/MCParser/MCAsmParser.h no longer includes llvm/MC/MCParser/MCAsmLexer.h
Preprocessed lines to build llvm on my setup:
after: 1068185081
before: 1068324320
So no compile time benefit to expect, but we still get the looser coupling
between files which is great.

There's a few relevant forward declarations in there that may require downstream
adding explicit includes:
llvm/MC/MCContext.h no longer includes llvm/BinaryFormat/ELF.h, llvm/MC/MCSubtargetInfo.h, llvm/MC/MCTargetOptions.h
llvm/MC/MCObjectStreamer.h no longer include llvm/MC/MCAssembler.h
llvm/MC/MCAssembler.h no longer includes llvm/MC/MCFixup.h, llvm/MC/MCFragment.h
Counting preprocessed lines required to rebuild llvm-project on my setup:
before: 1052436830
after: 1049293745
Which is significant and backs up the change in addition to the usual benefits of
decreasing coupling between headers and compilation units.

This reverts commit fd4808887e.
This patch causes gcc to issue a lot of warnings like:
warning: base class ‘class llvm::MCParsedAsmOperand’ should be
explicitly initialized in the copy constructor [-Wextra]
These instructions should allow src0 to be a literal with the same
value as the mandatory other literal. Enable it by introducing an
operand that defers adding its value to the MI when decoding till
the mandatory literal is parsed.

This moves the registry higher in the LLVM library dependency stack.
Every client of the target registry needs to link against MC anyway to
actually use the target, so we might as well move this out of Support.
This allows us to ensure that Support doesn't have includes from MC/*.

Maintain _V8 instruction variants of pseudo instructions allowing
assembly prior to GFX10 to work as-is. Currently the validator
can tell for GFX10 what the correct size is, so will disallow
oversize address registers.
