clang/HIP: Fix broken implementations of __make_mantissa* functions

The optimizer was folding the entire function to return 0. This
meant to be checking the character content of the pointer is the
string terminator, not null.

Also just make null inputs undefined. My docs for nanf say the
behavior of the argument is unspecified and segfaults on my system.
