[RISCV]Precommit test of D127568

Does this not also work as an asm test rather than an IR test?

This isn't an MC test. It's a Codegen test. Put in the codegen directory and update the title.

The issue is in RISCVTargetObjectFile.h which is part of the CodeGen layer not the MC layer. The MC layer uses RISCVMCObjectFileInfo already.

Move file to CodeGen test

Ideally, you just find where -mattr=-c,+relax is tested, add add the +c test there.

Add -NEXT whenever applicable.

16

remove trailing blank line

[StephenFan]

Use CHECK-NEXT is applicable.

Not ideally, I didn't find test files that testing with -mattr=-c,+relax :(
