iseq_add_mark_object is called in iseq_set_sequence later on,
so we only need to call iseq_add_mark_object_compile_time
in iseq_peephole_optimize. Without this change, there would've
been a duplicate entry in the long-lived iseq mark_ary.
* compile.c (iseq_peephole_optimize): avoid duplicate mark object entry

This is similar in spirit to opt_case_dispatch as the literal
Range here is guaranteed to be immutable when used for
checkmatch.
Normal range literals with non-frozen strings are actually
mutable, as Range#begin and Range#end exposes the strings to
modification. So those Range objects cannot be frozen without
breaking compatibility, but Ranges in case/when dispatch can be
frozen at compile time.
* compile.c (iseq_peephole_optimize): persistent Range creation
when String literals are used as beginning and end of range
when used for case/when dispatch.

Unfortunately this enlarges insns.def by yet another
instruction. However, it is much prettier than opt_str_freeze
in use, and maybe we can avoid having so many instructions in
the future.

There is an invariant that ISEQ_COVERAGE(iseq) must be Qnil if and only
if option->coverage_enabled is false. This invariant was broken by
NODE_PRELUDE which updates option->coverage_enabled but not
ISEQ_COVERAGE(iseq).

The same optimization used for "literal string".freeze
can easily apply to uminus without introducing any
compatibility problems.

Looking at the source code, FIXABLE tends to be just before LOING2FIX
to check applicability of that operation. Why not try computing first
then check for overflow, which should be optimial.
I also tried the same thing for unsigned types but resulted in slower
execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs.
