Support C99 hexadecimal floating-point literals in assembly It's useful to be able to write down floating-point numbers without having to worry about what they'll be rounded to (as C99 discovered), this extends that ability to the MC assembly parsers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188370 91177308-0d34-0410-b5e6-96231b3b80d8

MC/AsmParser: Support .single and .double for embedding floating point literals. - I believe more modern 'gas' supports a more enhanced set of arithmetic on them, but for now the only thing we can do is emit them as data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114719 91177308-0d34-0410-b5e6-96231b3b80d8
