[PATCH] Fix tree-vect-generic.c BIT_FIELD_REF creation (PR middle-end/52750)

Hi! The attached testcase shows that already for 32x signed char vector shuffles using the index element type for computing BIT_FIELD_REF positions is wrong - bytes 16 and above in the vector are bits 128 and above, and if idx has signed char type, that overflows. Fixed thusly, bootstrapped/regte
