compiler_rt: fix and improve documentation
- In Integer Bit Operations, use zeros consistently and fix the incorrect function descriptions - In ucmp, fix the incorrect signedness of the operands - In Integer Arithmetic, document the signedness of the operands in div, udiv, mod, umod, udivmod and divmod as it is done in LLVM documentation - In Float Conversion, replace "int_to_float" to "int to float" and "uint_to_float" to "uint to float"
