[9/77] Add SCALAR_FLOAT_TYPE_MODE
This patch adds a macro that extracts the TYPE_MODE and forcibly
converts it to a scalar_float_mode. The forcible conversion
includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P.
This becomes important as more static type checking is added by
later patches. It has the additional benefit of bypassing the
VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition
in TYPE_MODE; in release builds the new macro is a simple
field access.
