Debugify is extremely useful as a testing and debugging tool, and a good
number of LLVM-IR transform tests use it. We need it to support "new"
non-instruction debug-info to get test coverage, but it's not important
enough to completely convert right now (and it'd be a large
undertaking). Thus: convert to/from dbg.value/DPValue mode on entry and
exit of the pass, which gives us the functionality without any further
work. The cost is compile-time, but again this is only happening during
tests.
Tested by: the large set of debugify tests enabled here. Note the
InstCombine test (cast-mul-select.ll) that hasn't been fully enabled:
this is because there's a debug-info sinking piece of code there that
hasn't been instrumented.
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Vectorizer tests in the target-independent directory should not have a target
triple. If a test really needs to query a specific backend, it belongs in the
right target subdirectory (which "REQUIRES" the right backend). Otherwise, it
should not specify a triple.

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))

"Unroll" is not the appropriate name for this variable. Clang already uses
the term "interleave" in pragmas and metadata for this.
