[AIX][XCOFF] created a test case to verify the raw text section of xcoffobject file SUMMARY: in the patch https://reviews.llvm.org/D66969 . we need a test case to verify the out text section of the xcoffobject file is correct or not. but we do not have llvm disassembly tools to dump the xcoffobjectfile . since we commit the patch https://reviews.llvm.org/D70255, we have tools for it. we create this test case for it.

[llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713
