delocate: support floating point literals in AArch64 asm.

fcmp supports comparing a register against zero without needing to load
zero into a register. This is expressed in the asm as:

   fcmp d0, #0.0

I.e. a literal floating-point zero, which delocate cannot currently
parse.

LLVM starts generating such instructions with [1].
