Considering the issues Jeffrey Law has brought up, a function that calls itself
recursively for subexpressions seems to be a better fit.

doc/tm.texi also advertises the use of decl_overlaps_hard_reg_set_p for use in
target ports; in order to make this function really useful, it should
incorporate this scanning of subexpressions.  Its only current target-specific
use, in cris/cris.c , also seems like it would make more sense if this
was included.
