Fix PR 71873 - ICE in push_reload
Extend computation of subreg_in_class to constants and plus expressions
inside SUBREGs, before recursively calling push_reload. SYMBOL_REFs are
also CONSTANT_P, so remove explicit handling of SYMBOL_REFs.

* reload.c (push_reload): Compute subreg_in_class for
subregs of constants and plus expressions. Remove special
handling of SYMBOL_REFs.
