Oleg Ranevskyy 7232f66051 [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`).

Jim Grosbach 2987c57924 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.
