i386: Fix up *<dwi>3_doubleword_mask [PR105911]
Another regression caused by my recent patch.
This time because define_insn_and_split only requires that the
constant mask is const_int_operand. When it was only SImode,
that wasn't a problem, HImode neither, but for DImode if we need
to and the shift count we might run into a problem that it isn't
a representable signed 32-bit immediate.
But, we don't really care about the upper bits of the mask, so
we can just mask the CONST_INT with the mode mask.

* config/i386/i386.md (*ashl<dwi>3_doubleword_mask,
*<insn><dwi>3_doubleword_mask): Use operands[3] masked with
(<MODE_SIZE> * BITS_PER_UNIT) - 1 as AND operand instead of
operands[3] unmodified.
* gcc.dg/pr105911.c: New test.
