 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)
