The code patched here is counting how many registers the current
function would need to save in the prologue before it uses them.
The code is called per function, so using crtl is OK.

* haifa-sched.c: Include function-abi.h.
(alloc_global_sched_pressure_data): Use crtl->abi to check whether
the function would need to save a register before using it.
