re PR rtl-optimization/55717 (ICE in form_sum, at reload.c:5400)
PR debug/55717
* rtlhooks-def.h (RTL_HOOKS_GEN_LOWPART_NO_EMIT): Define to
gen_lowpart_if_possible.
(gen_lowpart_no_emit_general): Remove prototype.
* rtlhooks.c (gen_lowpart_no_emit_general): Removed.
* simplify-rtx.c (simplify_unary_operation_1,
simplify_binary_operation_1): Continue simplifying if
rtl_hooks.gen_lowpart_no_emit returns NULL_RTX.
* dwarf2out.c (mem_loc_descriptor) <case TRUNCATE>: Handle
truncation like lowpart SUBREG.
* testsuite/g++.dg/opt/pr55717.C: New test.
