[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC) 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.

Don't intentionally try to ignore the value of a scalar expression when we actually care about it. Fixes PR7291. llvm-svn: 105404 2010-06-04 03:58:07 +08:00			`// PR7291`

[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions. I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default.

IRgen: Assignment to Objective-C properties shouldn't reload the value (which would trigger an extra method call). - While in the area, I also changed Clang to not emit an unnecessary load from 'x' in cases like 'y = (x = 1)'. llvm-svn: 107210 2010-06-30 06:00:45 +08:00			`// CHECK: store i32 42, i32* %{{.*}}`
