Austin Clements	f582778ee9	cmd/compile: emit sensible go_asm.h consts for big ints ... Currently, the compiler will emit any const that doesn't fit in an int64 to go_asm.h like #define const_stackPreempt constant.intVal{val:(*big.Int)(0xc000c06c40)} This happens because dumpasmhdr formats the constant.Value using the verb "%#v". Since constant.Value doesn't implement the GoString() method, this just prints the Go-syntax representation of the value. This happens to work for small integer constants, which go/constant represents directly as an int64, but not for integer constants that don't fit in an int64, which go/constant represents as a big.Int. Make these constants usable by changing the formatting verb to "%v", which will call the String() method, giving a reasonable result in all cases.
