- Move DEBUG_TYPE below includes
- Change unknown address space constant to be consistent with other
passes
- Grammar fixes in debug output

combineX86ShufflesRecursively can still only handle a maximum of 2 shuffle inputs but everything before it now supports any number of shuffle inputs.
This will be necessary for combining OR(SHUFFLE, SHUFFLE) patterns.

Summary: SamplePGO needs to check if it is legal to promote a target before it actually promotes it.

Since we have no call support and late linking we can produce code
only for used symbols. This saves compilation time, size of the final
executable, and size of any intermediate dumps.
Run Internalize pass early in the opt pipeline followed by global
DCE pass. To enable it RT can pass -amdgpu-internalize-symbols option.

For some reason the exception selector register must be a pointer (that's
assumed by SDag); on the other hand, it gets moved into an IR-level type which
might be entirely different (i32 on AArch64). IRTranslator needs to be aware of
this.

For targets with different addressing modes in each address space,
if this is dropped querying isLegalAddressingMode later with this
will give a nonsense result, breaking the isLegalUse assertions.
This is a candidate for the 4.0 release branch.

This is worse if the original constant is an inline immediate.
This should also be done for 64-bit adds, but requires fixing
operand folding bugs first.

Previously, we would hit UB (or the ISD::DELETED_NODE assert) if we
happened to replace a node during UpdateChains, because it would be
left in the list we were iterating over. This nulls out the pointer
when that happens so that we can avoid the issue.
Fixes llvm.org/PR31710

To simplify/clarify memory ownership, make leaks (as one was found/fixed
recently) harder to write, etc.
(also, while I was there - removed a duplicate lookup in a container)

This reverts commit r293196
Besides making things look nicer, ATM, we'd like to preserve analysis
more than we'd like to destroy the CFG. We'll probably revisit in the future

The original shift is bigger, so this may qualify as 'obvious',
but here's an attempt at an Alive-based proof:
Name: exact
Pre: (C1 u< C2)
%a = shl i8 %x, C1
%b = lshr exact i8 %a, C2
=>
%c = lshr exact i8 %x, C2 - C1
%b = and i8 %c, ((1 << width(C1)) - 1) u>> C2
Optimization is correct!
