use the last passed -munaligned-access / -mno-unaligned-access Passing inconsistent munaligned-access / mno-unaligned-access flags, intentionally resulted in a warning and the flag no-unaligned-access being used. Gcc does, at least in practice, use the last flag in such a case.

Fix up handling of ARM options for controlling strict alignment. The -mstrict-align option was originally added in r167619 as a target- independent option. It was then changed in r167623 to be implemented with an ARM-specific backend option, even though the code remained in the target-independent Clang::ConstructJob function. This means that if you used the -mstrict-align option with a non-ARM target, you would still get the -arm-strict-align option getting passed to the backend, which was harmless but gross. The driver option was then replaced by the GCC-compatible -m[no-]unaligned-access option (r189175) and modified to work with AArch64 (r208075). However, in the process, the help text for -mstrict-align was incorrectly changed to show it as only being supported for AArch64. Even worse, the logic for handling these options together with -mkernel was wrong for AArch64, where -mkernel does not currently imply strict alignment. This patch fixes up all of those things. Besides the obvious change to the option help text, it moves the logic into the ARM and AArch64-specific parts of the driver, so that the option will be correctly ignored for non-ARM targets. <rdar://problem/17823697> llvm-svn: 214148
