  clang: Add  __builtin_elementwise_fma

I didn't understand why the other builtins have promotion logic,
or how it would apply for a ternary operation. Implicit conversions
are evil to begin with,  and even more so when the purpose is to get
an exact IR intrinsic. This checks all the arguments have the same type.
