[clang] Disallow fbasic-block-sections on non-ELF, non-x86 targets. Basic block sections is untested on other platforms and binary formats apart from x86,elf. This patch emits a warning and drops the flag if the platform and binary format are not compatible. Add a test to ensure that specifying an incompatible target in the driver does not enable the feature. Differential Revision: https://reviews.llvm.org/D87426
