Patch fixing the regression.
Hi!
171731 introduces an access macro reg_equiv_mem(), which is now used in the VAX
backend. However, the header file isn't included, so the VAX backend (tested
for --target=vax-linux) now breaks:

The attached patch fixes this regression by including the header file defining
the used macro. (ChangeLog is in the patch file, needs the PR number.)
