Log:
[38/77] Move SCALAR_INT_MODE_P out of strict_volatile_bitfield_p

strict_volatile_bitfield_p returns false for any mode that isn't
a scalar integer.  This patch moves the check to the caller and
makes strict_volatile_bitfield_p take the mode as a scalar_int_mode.
The handling of a true return can then also use the mode as a
scalar_int_mode.

gcc/
	* expmed.c (strict_volatile_bitfield_p): Change the type of fieldmode
	to scalar_int_mode.  Remove check for SCALAR_INT_MODE_P.
	(store_bit_field): Check is_a <scalar_int_mode> before calling
	strict_volatile_bitfield_p.
	(extract_bit_field): Likewise.
