Justin Bogner eaae305a09 update_mir_test_checks: Improve the check for LLVM IR in MIR files
The LLVM IR section of a MIR document can start with "--- |" rather
than just "---", because "|" is a sigil for a freeform document in
YAML. We need to handle this so that we don't try to add check lines
to the LLVM IR functions in a MIR file.

Justin Bogner 4314f3adc2 update_mir_test_checks: Accept IR as input as well as MIR
We need to handle IR for tests that want to do lowering (or just
-stop-after with IR as input). I've run this on one AArch64 test to
demonstrate what it looks like.

Justin Bogner 930a95c269 update_mir_test_checks: Add "mir" to some states and regex names
For tests that do lowering we need to support IR as input, so here we
clarify some names to avoid ambiguity in upcoming commits.

Justin Bogner f7b1007345 update_mir_test_checks: Be careful about replacing entire vregs
Previously, this could end up replacing a vreg like %14 with
[[VREG1]]4, where VREG1 was the match for %1. That's obviously not
correct, though it hasn't actually come up in any tests I've converted
so far.

Justin Bogner da9600e646 update_mir_test_checks: Support adding checks for vreg classes
This is a temporary hack to support adding checks for the "registers:"
block of mir functions. This is necessary to convert a number of tests
so that there's less churn when we change the MIR printer to put the
vreg classes on defs instead of in their own block.

Justin Bogner 3de36d6f11 update_mir_test_checks: Handle empty liveins
An empty livein block doesn't make much sense (why not just omit it?)
but they're legal and some tests have them, so its best to handle it.

Justin Bogner 1a33cdb2e2 update_mir_test_checks: Do a better job of disambiguating names
Matching prefixes isn't good enough, because it leads to things like
calling the first constant C3 just because there were two copies
before it. Tighten up the check to match more precisely, but also be
careful about ambiguity when dealing with target opcodes that end in a
number.

Some AArch64 and AMDGPU tests have functions with hyphens in the names

Justin Bogner cf30db922e update_mir_test_checks: Fix a typo I made while preparing for commit
I accidentally added an extra arg here, so this didn't work at all.

Justin Bogner 7c1bdaf7ca Add a utility to update MIR checks, similar to update_llc_test_checks
This adds update_mir_test_checks, which updates the check lines in mir
tests. This can only update tests that start and end with .mir
currently (ie, -run-pass) but it should be sufficient for updating at
least some of the GlobalISel tests.
