Please merge c01c62c76c60a5a5da0496e41faae907944c92dd (regression, trivial fix) – [MC][ELF] Fix accepting abbreviated form with Type change

[tob2]

Trivial change (silence bogus error), which is a regression.

@tstellar – Please merge c01c62c (cf. also D114717 ) into 13.0.1 (→ 13.0.1 Meta Issue #51489).

Change is just the following to silence an error (+ moving a comment + testcase):

-  if (Section->getType() != Type &&
+  if (!TypeName.empty() && Section->getType() != Type &&
       !allowSectionTypeMismatch(getContext().getTargetTriple(), SectionName,
                                 Type))
     Error(loc, "changed section type for " + SectionName + ", expected: 0x" +
                    utohexstr(Section->getType()));

@tstellar Safe. Please backport.

This fails to cherry-pick cleanly. Can someone resolve the conflicts and push to a fork on github?

[MaskRay]

The conflict was due to missing 990e802 ([MC][ELF] Do not error on parsing .debug_* section directive for MIPS), which was worth merging as well. Merged it and [MC][ELF] Fix accepting abbreviated form with Type change into release/13.x.
