LRA: Implement combining secondary memory reload and original insn

LRA creates secondary memory reload insns but do not try to combine it
with the original insn.  This patch implements a simple insn combining
for such cases in LRA.

        PR rtl-optimization/109052

gcc/ChangeLog:

* lra-constraints.cc: Include hooks.h.
(combine_reload_insn): New function.
(lra_constraints): Call it.

gcc/testsuite/ChangeLog:

* gcc.target/i386/pr109052.c: New.
