load instruction
Essentially the same as the GEP change in r230786.
A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)
import fileinput
import sys
import re
pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")
for line in sys.stdin:
sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

Summary:
When I initially introduced -pass-remarks, I thought it would be a
neat idea to make it additive. So, if one used it as:
$ llc -pass-remarks=inliner --pass-remarks=loop.*
the compiler would build the regular expression '(inliner)|(loop.*)'.
The more I think about it, the more I regret it. This is not how
other flags work. The standard semantics are right-to-left overrides.
This is how clang interprets -Rpass. And I think the two should be
compatible in this respect.

Summary:
This adds support in 'opt' to filter pass remarks emitted by
optimization passes. A new flag -pass-remarks specifies which
passes should emit a diagnostic when LLVMContext::emitOptimizationRemark
is invoked.
This will allow the front end to simply pass along the regular
expression from its own -Rpass flag when launching the backend.
Depends on D3227.
