Replace individual operands GLC, SLC, and DLC with a single cache_policy
bitmask operand. This will reduce the number of operands in MIR and I hope
the amount of code. These operands are mostly 0 anyway.
Additional advantage that parser will accept these flags in any order unlike
now.

gfx1030 added a new way to implement readcyclecounter using the
SHADER_CYCLES hardware register, but the s_memtime instruction still
exists, so the MC layer should still accept it and the
llvm.amdgcn.s.memtime intrinsic should still work.

As we don't sort local symbols, don't sort non-local symbols. This makes
non-local symbols appear in their register order, which matches GNU as. The
register order is nice in that you can write tests with interleaved CHECK
prefixes, e.g.
```
// CHECK: something about foo
.globl foo
foo:
// CHECK: something about bar
.globl bar
bar:
```
With the lexicographical order, the user needs to place lexicographical smallest
symbol first or keep CHECK prefixes in one place.
Add mimgopc object to represent the opcode allowing different
opcodes for different hardware variants.

GNU as does not sort local symbols. This has several advantages:
* The .symtab order is roughly the symbol occurrence order.
* The closest preceding STT_SECTION symbol is the definition of a local symbol.
* The closest preceding STT_FILE symbol is the defining file of a local symbol, if there are multiple default-version .file directives. (Not implemented in MC.)
Support for XNACK and SRAMECC is not static on some GPUs. We must be able
to differentiate between different scenarios for these dynamic subtarget
features.
The possible settings are:
- Unsupported: The GPU has no support for XNACK/SRAMECC.
- Any: Preference is unspecified. Use conservative settings that can run anywhere.
- Off: Request support for XNACK/SRAMECC Off
- On: Request support for XNACK/SRAMECC On
GCNSubtarget will track the four options based on the following criteria. If
the subtarget does not support XNACK/SRAMECC we say the setting is
"Unsupported". If no subtarget features for XNACK/SRAMECC are requested we
must support "Any" mode. If the subtarget features XNACK/SRAMECC exist in the
feature string when initializing the subtarget, the settings are "On/Off".
The defaults are updated to be conservatively correct, meaning if no setting
for XNACK or SRAMECC is explicitly requested, defaults will be used which
generate code that can be run anywhere. This corresponds to the "Any" setting.

This patch sets the default for llvm tests, with the exception of tests
under Reduce, because quite a few of them use 'FileCheck' as parameter
to a tool, and including a flag as that parameter would complicate
matters.
The rest of the patch undo-es the lit.local.cfg changes we progressively
introduced as temporary measure to avoid regressions under various
directories.
Differential Revision: https://reviews.llvm.org/D95111
This patches remaining tests, and patches lit.local.cfg to block future
such cases (until we flip FileCheck's flag)

The following large tests have been split into smaller parts by instruction formats:
gfx7_asm_all.s
gfx8_asm_all.s
gfx9_asm_all.s
gfx10_asm_all.s
This change results in noticeable lit testing speedup.
For example, on a debug Windows build, split asm tests are run 3.5 times faster.
I think the global_load/store_dword_addtid instructions support
switching off the scalar address.
Add assembler and disassembler support for this.

Revert part of https://reviews.llvm.org/D92084 to make it simpler to
start consuming the EndOfStatement token within AMDGPU's
ParseInstruction in a future patch. This also brings us back to what
every other target currently does.
A future change to move the position back to the end of the statement
would likely need to audit all of the AMDGPUOperand SMLoc ranges, and
determine the SMLoc for the last character of the last operand.
