c-common.h (c_common_print_pch_checksum): Remove.

c-family/
	* c-common.h (c_common_print_pch_checksum): Remove.
	* c-pch.c: Do not include output.h.
	(CHECK_NO_ASM_OUT_DURING_PCH): Define and add FIXME.
	(asm_out_file): Define iff CHECK_NO_ASM_OUT_DURING_PCH isdefined.
	(asm_file_startpos): Define iff CHECK_NO_ASM_OUT_DURING_PCH is defined.
	(struct c_pch_header): Remove.
	(get_ident): Update gpch version.
	(pch_init): Do not print executable_checksum to asm_out_file.
	Do not fail if there is no asm_out_file to read back from.  Set
	asm_file_startpos only if CHECK_NO_ASM_OUT_DURING_PCH is defined.
	(c_common_write_pch): Verify that nothing was written to asm_out_file
	since pch_init was called.  Do not write a c_pch_header, and do not
	copy from asm_out_file to the PCH.
	(c_common_read_pch): Do not read a c_pch_header, and do not restore
	the content of asm_out_file from the PCH.
	(c_common_print_pch_checksum): Remove.
	* c-opts.c (c_common_init): Print out executable_checksum directly.

testsuite/
	* testsuite/gcc.dg/pch/ident-1.c: New test.
	* testsuite/gcc.dg/pch/ident-1.hs: Header file for new test.
