emit-rtl.h (replace_equiv_address, [...]): Add an inplace argument.

gcc/
	* emit-rtl.h (replace_equiv_address, replace_equiv_address_nv): Add an
	inplace argument.  Store the new address in the original MEM when true.
	* emit-rtl.c (change_address_1): Likewise.
	(adjust_address_1, adjust_automodify_address_1, offset_address):
	Update accordingly.
	* rtl.h (plus_constant): Add an inplace argument.
	* explow.c (plus_constant): Likewise.  Try to reuse the original PLUS
	when true.  Avoid generating (plus X (const_int 0)).
	* function.c (instantiate_virtual_regs_in_rtx): Adjust the PLUS
	in-place.  Pass true to plus_constant.
	(instantiate_virtual_regs_in_insn): Pass true to replace_equiv_address.
