This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.
Differential Revision: https://reviews.llvm.org/D123115
Discussed with @craig.topper and @spatel - this is to try and tidyup the codegen folder and move the x86 specific tests (as opposed to general tests that just happen to use x86 triples) into subfolders. Its up to other targets if they follow suit.
It also helps speed up test iterations as using wildcards on lit commands often misses some filenames.
