analyses in the new pass manager.
These just handle really basic stuff: turning a type name into a string
statically that is nice to print in logs, and getting a static unique ID
for each analysis.
Sadly, the format of passes in anonymous namespaces makes using their
names in tests really annoying so I've customized the names of the no-op
passes to keep tests sane to read.
This is the first of a few simplifying refactorings for the new pass
manager that should reduce boilerplate and confusion.

Add parsing and printing of image operands. Matches legacy sp3 assembler.
Change image instruction order to have data/image/sampler operands in the beginning. This is needed because optional operands in MC are always last.
Update SITargetLowering for new order.
Add basic MC test.
Update CodeGen tests.

Instead of the convoluted if-statment we can just use getColor. This also fixes
a bug where we relied upon the parity of tablegen-generated register indexes
(instead of using the machine encoding).

These diagnostics aren't perfect - in the case of merging several dwos
into dwps and those dwps into more dwps - just getting the message about
the original source file name might not be much help (since it's the
same in both dwos, by definition - but doesn't tell you which chain of
dwps to backtrack)
It might be worth adding the DW_AT_dwo_id to the split debug info to
improve the diagnostic experience - might help track down the duplicates
better.

Though a bit odd, this is handy for a few reasons - for example, in a
build system that wants consistent input/output of build steps, but
where split-dwarf might be overriden/disabled by the user on a per-file
basis.

Currently aligned is what is being used so remove the redundant patterns for the unaligned versions. But don't do this for the byte and word vector types since they don't have aligned versions.

This also simplifies the code by removing the overly conservative
NoInterveningSideEffect() function. This function checked:
- That the two copies belong to the same block: We only process one
block at a time and clear our maps in between it is impossible to find a
copy from a different block.
- There is no terminator between the two copy instructions: This is not
allowed anyway (the MachineVerifier would complain)
- Does not have instructions with hasUnmodeledSideEffects() or isCall()
set: Even for those instructuction we must have all clobbers/defs of
registers explicit as an operand. If the register is explicitely
clobbered we would never come to the point of checking for
NoInterveningSideEffect() anyway.
(I also checked this with a temporary build of the test-suite with all
potentially failing conditions in NoInterveningSideEffect() turned into
asserts)

Summary: Check that we're using SCEV for the same loop we're simulating. Otherwise, we might try to use the iteration number of the current loop in SCEV expressions for inner/outer loops IVs, which is clearly incorrect.

Summary:
This is the first simple attempt to reduce number of coverage-
instrumented blocks.
If a basic block dominates all its successors, then its coverage
information is useless to us. Ingore such blocks if
santizer-coverage-prune-tree option is set.

Inline-asm calls aren't annotated with funclet bundle operands because
they don't throw and cannot be inlined through. We shouldn't require
them to bear an funclet bundle operand.

Summary:
Avoid special case for FP, LR CFI emission and just allow general
AArch64FrameLowering::emitCalleeSavedFrameMoves() to handle them. Also,
stop recalculating the stack offsets in emitCalleeSavedFrameMoves()
since we can just reuse the previously calculated offset stored in the
MachineFrameInfo.
