ira: Fix unnecessary register spill
The variables first_moveable_pseudo and last_moveable_pseudo aren't
reset after compiling a function, which means they leak into the first
scheduler pass of the following function. In some cases, this can cause
an extra spill during register allocation of the second function.
gcc/ChangeLog:
* ira.c (move_unallocated_pseudos): Zero first_moveable_pseudo and
last_moveable_pseudo before returning.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/nospill.c: New test.
