Log:
[TLI] Fix NumParams==0 prototype checking typo.
There was a typo in r267758. It caused invalid accesses when
given something like "void @free(...)", as NumParams == 0, and
we then try to look at the 0th parameter.
Turns out, most of these were untested; add both attribute
and missing-prototype checks for all libc libfuncs.
