* stmt.c (expand_asm_operands): Twiddle generating_concat_p

so that CONCATs are not generated for ASMs.
* emit-rtl.c (gen_reg_rtx): Don't generate CONCATs when
not generating_concat_p.
* function.c (pop_function_context_from): Reset
generating_concat_p.
(prepare_function_start): Likewise.
* rtl.c (generating_concat_p): Define.
* rtl.h (generating_concat_p): Declare.
* toplev.c (rest_of_compilation): No CONCATs after RTL generation.
