We currently put everything in one single archive libc.a which breaks in certain situations where the compiler drivers expect libm.a also. With this change, we separate out libc.a and libm.a functions as is done conventionally and put them in two different static archives. One will now have to build two targets, `libc` and `libm` which produce `libc.a` and `libm.a` respectively. Under default build, one still builds only one target named `libc` which produces `libllvmlibc.a`. Reviewed By: jhuber6 Differential Revision: https://reviews.llvm.org/D143005
