The 'G' constraint only matches a float zero, so it will never match in integer
move patterns.
Tested on hppa-unknown-linux-gnu. Committed to active branches.

Mostly, I just worry about losing the key test for the FSM

This patch provides RTL expanders to implement logical shifts and
rotates of 128-bit values (stored in vector integer registers) by
constant bit counts. Previously, GCC would transfer these values
to a pair of scalar registers (TImode) via memory to perform the
operation, then transfer the result
