  Log Message:
  [Sparc] Don't use SunStyleELFSectionSwitchSyntax

As discussed in D85414 <https://reviews.llvm.org/D85414>, two tests
currently `FAIL` on Sparc since that backend uses the Sun assembler syntax
for the `.section` directive, controlled by

Instead of adapting the affected tests, this patch changes that default.
The internal assembler still accepts both forms as input, only the output
syntax is affected.

Current support for the Sun syntax is cursory at best: the built-in
assembler cannot even assemble some of the directives emitted by GCC, and
the set supported by the Solaris assembler is even larger: SPARC Assembly
Language Reference Manual, 3.4 Pseudo-Op Attributes

A few Sparc test cases need to be adjusted. At the same time, the patch
fixes the failures from D85414 <https://reviews.llvm.org/D85414>.

Tested on `sparcv9-sun-solaris2.11`.
