re PR c++/88482 (ICE when wrongly declaring __cxa_allocate_exception)
PR c++/88482
* except.c (verify_library_fn): New function.
(declare_library_fn): Use it. Initialize TM even if the non-TM
library function has been user declared.
(do_end_catch): Don't set TREE_NOTHROW on error_mark_node.
(expand_start_catch_block): Don't call initialize_handler_parm
for error_mark_node.
(build_throw): Use verify_library_fn. Initialize TM even if the
non-TM library function has been user declared. Don't crash if
any library fn is error_mark_node.
* g++.dg/eh/builtin5.C: New test.
* g++.dg/eh/builtin6.C: New test.
* g++.dg/eh/builtin7.C: New test.
* g++.dg/eh/builtin8.C: New test.
* g++.dg/eh/builtin9.C: New test.
* g++.dg/eh/builtin10.C: New test.
* g++.dg/eh/builtin11.C: New test.
* g++.dg/parse/crash55.C: Adjust expected diagnostics.
* eh_cpp.cc (__cxa_throw): Change DEST argument type from
void * to void (*) (void *).
(_ITM_cxa_throw): Likewise.
* libitm.h (_ITM_cxa_throw): Likewise.
* libitm.texi (_ITM_cxa_throw): Likewise.
