[libc-commits] [libc] [libc][arm] add more math.h entrypoints (PR #77839)

[Nick Desaulniers via libc-commits]

https://github.com/nickdesaulniers created https://github.com/llvm/llvm-project/pull/77839

In particular, we have internal customers that would like to use nanf and
scalbnf.

The differences between various entrypoint files can be checked via:

    $ comm -3 <(grep libc\.src path/to/entrypoints.txt | sort) \
       <(grep libc\.src path/to/other/entrypoints.txt | sort)
