Log Message:
gcc: vax: indicate to GCC that bitfield instructions may trap on VAX
Bitfield instructions will generate a reserved operand fault if the
operands are not reasonable (size > 32, position > 31 and size not
zero and field in a register). GCC generates code to test for these
conditions but in certain circumstances, the optimiser may decide that
a bitfield extraction instruction is invariant and move it ahead of
the instructions testing its arguments.
Introduce a new target hook to indicate to GCC that a bitfield
instruction may trap and update may_trap_p_1()
