I am working on making FileCheck stricter (in D54769 and D53710) so that it
issues diagnostics when there's something wrong with tests.
This is a cleanup for dangling prefixes in the ARM codegen tests, e.g.:
--check-prefixes=A,B
where A occurs in the check file, but B doesn't. This can be innocent if A does
all the required checking, but can also be a bug in that test if it results in
the test actually not checking anything (if A for example only checks a common
label). Test CodeGen/ARM/smml.ll is such an example.

The ARM Runtime ABI document (IHI0043) defines the AEABI floating point
helper functions in section 4.1.2 The floating-point helper functions.
The functions listed in this section must always use the base AAPCS calling
convention.
This test generates calls to all the helper functions that llvm supports
and checks that the base AAPCS calling convention has been used. We test
the equivalent of -mfloat-abi=soft, -mfloat-abi=softfp, -mfloat-abi=hardfp
with an FPU that supports single and double precision, and one that only
supports double precision.
