Oliver Stannard bb4c357000 [ARM] Fix unwind information for floating point registers
Fixes the unwind information generated for floating-point registers.
Previously, all padding registers were assumed to be four bytes wide. Now, the
width of the register is used to specify the amount of padding.

Patch by Jackson Woodruff!
