Changes in this patch:

- When lowering floating-point masked gathers, cast the result of the gather back to the original type with reinterpret_cast before returning.
- Added patterns for reinterpret_casts from integer to floating point, and concat_vector patterns for bfloat16.
- Tests for various legalisation scenarios with floating point types.
