- add -ppc-reg-with-percent-prefix option to use %r3 etc as register
names
- split off logic for Darwinish verbose conditional codes into a helper
function
- be explicit about Darwin vs AIX vs GNUish assembler flavors

This class had some code that would automatically remap type
indices before hashing and serializing. The only caller of
this method was the TypeStreamMerger anyway, and the method
doesn't make general sense, and prevents making certain future
improvements to the class. So, factoring this up one level
into the TypeStreamMerger where it belongs.

If we put in an assertsext/zext here, we're able to generate better truncate code using pack on pre-avx512 targets.
Similar is already done during type legalization. This is the equivalent for op legalization

To fully avoid trapping on wasm, fptoui needs a second check to ensure that
the operand isn't below the supported range.

A couple of places in LLD were passing references to
TypeTableCollections around, which makes it hard to change the
implementation at runtime. However, these cases only needed to
iterate over the types in the collection, and TypeCollection
already provides a handy abstract interface for this purpose.
By implementing this interface, we can get rid of the need to
pass TypeTableBuilder references around, which should allow us
to swap the implementation at runtime in subsequent patches.

Partially reverting enabling of post-legalization store merge
(r319036) for just ARM backend as it is causing incorrect code

Instead, reuse the code-path for cl.exe that adds /W4 , which for clang-cl
aliases clang's "-Wall -Wextra" which matches what clang-cl's /Wall
previously aliased.
This should restore the verbosity of a Windows selfhost build back to
its previous levels.

When lowering a G_BRCOND, we generate a TSTri of the condition against
1, which sets the flags, and then a Bcc which branches based on the
value of the flags.
Unfortunately, we were using the wrong condition code to check whether
we need to branch (EQ instead of NE), which caused all our branches to
do the opposite of what they were intended to do. This patch fixes the
issue by using the correct condition code.

When translating pseudo to MC, v_add/sub/subrev_u32 shall be mapped via a separate table as GFX8 has opcodes with the same names.
These instructions shall also be labelled as renamed for pseudoToMCOpcode to handle them correctly.

If common type is different we should bail out due to we will not be
able to create a select or Phi of these values.
Basically it is done in ExtAddrMode::compare however it does not work
if we handle the null first and then two values of different types.
so add a check in initializeMap as well. The check in ExtAddrMode::compare
is used as earlier bail out.

Separate the handling of AND/AND8 out from PHI/OR/ISEL checking. The reasoning
is the others need all their operands to be sign/zero extended for their output
to also be sign/zero extended. This is true for AND and sign-extension, but for
zero-extension we only need at least one of the input operands to be zero
extended for the result to also be zero extended.

The object can't straddle the address space
wrap around, so I think it's OK to assume any
offsets added to the base object pointer can't
overflow. Similar logic already appears to be
applied in SelectionDAGBuilder when lowering
aggregate returns.

GFX9 stopped using m0 for most DS instructions. Select
a different instruction without the use. I think this will
be less error prone than trying to manually maintain m0
uses as needed.
