re PR target/60568 (lto1: internal compiler error: in insn_min_length, at config/i386/i386.md:1599)

	PR target/60568
	* config/i386/i386.c (x86_output_mi_thunk): Surround UNSPEC_GOT
	into CONST, put pic register as first operand of PLUS.  Use
	gen_const_mem for both 32-bit and 64-bit PIC got loads.
