Fix ICE in ix86_attr_length_immediate_default.
ix86_attr_length_immediate_default assume TYPE ishift only have 1
constant operand,
but *x86_64_shld_1/*x86_shld_1/*x86_64_shrd_1/*x86_shrd_1 has 2, with
condition: INTVAL (operands[3]) == 32 - INTVAL (operands[2]) or
INTVAL (operands[3]) == 64 - INTVAL (operands[2]), and hit
gcc_assert.
Explicitly set_attr length_immediate for these patterns.
