Hi,

The original patch supported matching the 
vect_recog_bitfield_ref_pattern for
BITFIELD_REF's where the first operand didn't have a INTEGRAL_TYPE_P type.
That means it would also match vectors, leading to regressions in 
targets that
supported vectorization of those.

Bootstrappend and regression tested on aarch64-none-linux-gnu and 
x86_64-pc-linux-gnu.
