Some of the update_*_test_checks regexes have been moved into a
library, so we might as well use them in update_mir_test_checks.
Also includes minor bugfixes to the regexes that are there so we
don't regress update_mir_test_checks

Since vregs are printed in the instruction stream now, checking the
vreg block is always redundant. Remove the temporary feature that
allowed us to do that.
This reverts r316134

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.
llvm-svn: 323178
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.

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.
llvm-svn: 317509
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.
llvm-svn: 316134
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.
llvm-svn: 316089
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.
llvm-svn: 316088
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.
