Also add mappings for single and double precision FP, and use them for G_FADD
and G_LOAD.

Add a register bank for floating point values and select simple instructions
using them (add, copies from GPR).
This assumes that the hardware can cope with a single precision add (VADDS)
instruction, so the legalizer will treat G_FADD as legal and the instruction
selector will refuse to select if the hardware doesn't support it. In the future
we'll want to be more careful about this, and legalize to libcalls if we have to
use soft float.

Summary:
This patch tablegen-erates the ARM register bank information so that the
static tables added in D27807 no longer need to be maintained.
Depends on D27338
