Log Message:
Step 1 of getting gcc to generate VAX PIC code again.  These steps are being
committed in "smallish" steps.  This step incorporates the switch to MEM_P,
REG_P, and CONST_INT_P.  Use bool/true/false where appropriate.  PRINT_OPERAND
moves from being a large macro in vax.h print_operand in vax.c.  Fix rtx cost
for a constant of 0.  This eliminates unneeded moves when setting to 0 would
be fine.

Lastly, include completely new (on by default) code for DImode move, addition,
and subtract.  This code is significantly faster and smaller that what existed
before.
