Update Transforms tests to use CHECK-LABEL for easier debugging. No functionality change.

[opaque pointer type] Add textual IR support for explicit type parameter to 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"((?:=\|:\|^)\sload (?: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)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230794 91177308-0d34-0410-b5e6-96231b3b80d8 2015-02-27 21:17:42 +00:00			`%r = load atomic i32, i32* %a seq_cst, align 4`
