I blindly applied the patch without looking at the previous changes!)

If you revert the changes, don't forget to update
gcc/testsuite/gfortran.dg/spread_size_limit.f90.
Also I see a small slow down for the test in pr34554 (gfc is patched, gfcp
not):
[macbook] f90/bug% time gfc pr34554.f90
259.917u 0.168s 4:20.44 99.8% 0+0k 0+29io 0pf+0w
[macbook] f90/bug% a.out
152 135210384
[macbook] f90/bug% time gfcp pr34554.f90
249.102u 0.129s 4:09.39 99.9% 0+0k 1+22io 0pf+0w
[macbook] f90/bug% a.out
152 135210384
Also the timing (with/without patch) for a variant of pr19925 is:
[macbook] f90/bug% time gfc pr19925_1.f90 -fmax-array-constructor=100000
3.038u 0.175s 0:03.22 99.3% 0+0k 0+16io 0pf+0w
So, is the machinery around -fmax-array-constructor still needed?
