re PR target/47564 (internal compiler error in memory_address_addr_space, at explow.c:504)
PR target/47564
* toplev.c (target_reinit): Save and restore *crtl and regno_reg_rtx
around backend_init_target and lang_dependent_init_target calls.
* cgraphunit.c (cgraph_debug_gimple_stmt): New function.
(verify_cgraph_node): Don't call set_cfun here. Use
cgraph_debug_gimple_stmt instead of debug_gimple_stmt.
Set error_found for incorrectly represented calls to thunks.
* gcc.target/i386/pr47564.c: New test.
