Previously findClosestSuitableAluInstr was only considering the base register when checking the current instruction for suitability. Expand check to consider the offset if the offset is a register.

Differentiate between word and subword memory operations as they take different
amount of cycles to complete. This just adds a basic model of the subword
latency to the scheduler.

* Add lowering for SETCCE i32.
* Add test to check lowering of i64 compares uses SETCCE expansion (outside of EQ and NE).
* Fix select.ll test and immediate form selection for RI operations.

There's currently no raw_ostream &operator<<(SimpleValueType); provided by LLVM. It could be added by refactoring utils/TableGen/CodeGenTarget.cpp:getEnumName, but that's much more work than fixing the build.

Removed some unused headers, replaced some headers with forward class declarations.
Found using simple scripts like this one:
clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap'

Summary: LanaiSetflagAluCombiner could previously combine instructions across basic building blocks even when not legal. Make the LanaiSetflagAluCombiner more conservative to avoid this.

Summary:
This adds the same checks that were added in r264593 to all
target-specific passes that run after register allocation.

Summary:
* Fix to stop delay slot filler from inserting SP modifying instructions in the newly expanded call/return instructions.
* In LowerSymbol the outermost type was not LanaiMCExpr if there was a binary expression
* Remove printExpr in LanaiInstPrinter

This will become necessary in a subsequent change to make this method
merge adjacent stack adjustments, i.e. it might erase the previous
and/or next instruction.
It also greatly simplifies the calls to this function from Prolog-
EpilogInserter. Previously, that had a bunch of logic to resume iteration
after the call; now it just continues with the returned iterator.
Note that this changes the behaviour of PEI a little. Previously,
it attempted to re-visit the new instruction created by
eliminateCallFramePseudoInstr(). That code was added in r36625,
but I can't see any reason for it: the new instructions will obviously
not be pseudo instructions, they will not have FrameIndex operands,
and we have already accounted for the stack adjustment.

isBrImm should accept any non-constant immediate. Previously it was only accepting LanaiMCExpr ones which was wrong.
