Log Message:
gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [21/21]

Define separate instruction patterns for extzv for the cases where the fiel
d width and offset happen to be a multiple of a byte or word.

If in PIC mode, and the source operand to extzv is a memory
reference, and the address of the memory location is an external
symbol, load the address into a temporary register before expanding
the instruction.

Adjust the constraints to the zero_extract instruction pattern to
disallow indexed source operands, as the VAX extzv instruction
computes offsets based on the size of a byte (not a word or a
longword)
