-mcmodel= is supported for a few architectures. Reject the option for other architectures. * -mcmodel= is unsupported on x86-32. * -mcmodel=large is unsupported for PIC on AArch64. * -mcmodel= is unsupported for aarch64_32 triples. * https://reviews.llvm.org/D67066 (for RISC-V) made -mcmodel=medany/-mcmodel=medlow aliases for all architectures. Restrict this to RISC-V. * llvm/lib/Target/Sparc has some small/medium/large support, but the values listed on https://gcc.gnu.org/onlinedocs/gcc/SPARC-Options.html had been supported before https://reviews.llvm.org/D67066. Consider -mcmodel= unsupported for Sparc. * https://reviews.llvm.org/D106371 translated -mcmodel=medium to -mcmodel=large on AIX, even for 32-bit systems. Retain this behavior but reject -mcmodel= for other PPC32 systems. In general the accept/reject behavior is more similar to GCC. err_drv_invalid_argument_to_option is less clear than err_drv_unsupported_option_argument. As the supported values are different for different architectures, add a err_drv_unsupported_option_argument_for_target for better clarity.
