We use both -long-option and --long-option in tests. Switch to --long-option for consistency.
In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.
While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).

Remove a useless SwitchSection which also causes compilation failure
when IR contains comdat.
The SwitchSection is useless because the current section is already
correct text section for the function therefore no need to switch.
It causes compilation failure for comdat because functions with comdat
has specific text section, not the default .text section.
Since HIP uses comdat, this bug caused failures for HIP.
