In GO_IF_LREGITIMATE_ADDRESS(), use RTX_OK_FOR_BASE_P() to check for a
valid base register for indexed addressing, rather than providing an
incomplete inline version.
This allows constructs such as
(plus:SI (reg:SI (subreg:SI (reg:DI 1))))
to properly pass through the reload phase if optimization is enabled.
Such a construct can be generated with
buf[index + index2] = value;
if either index or index2 are long long.
Fixes the ICE in zsh Src/Zle/computil.c.
