Tests: check for target availability for target-specific tests. Lots of tests are using an explicit target triple w/o first checking that the target is actually available. Add a REQUIRES clause to a bunch of them. This should hopefully unbreak bots which don't configure w/ all targets enabled. llvm-svn: 159949

[CodeGen] Clang does not choose aapcs-vfp calling convention for ARM bare metal target with hard float (EABIHF) Summary: Clang does not detect `aapcs-vfp` for the EABIHF environment. The reason is that only GNUEABIHF is considered while choosing calling convention, EABIHF is ignored. This causes clang to use `aapcs` for EABIHF and add the `arm_aapcscc` specifier to functions in generated IR. The modified `arm-cc.c` test checks that no calling convention specifier is added to functions for EABIHF, which means the default one is used (`CallingConv::ARM_AAPCS_VFP`).
