* compile.c (iseq_peephole_optimize): remove unreachable jump
instruction only. if it is labeled and referred from other
instructions, it is reachable and must not be removed.
[ruby-core:87830] [Bug #14897]

Reading win32/win32.c waitpid implementation, maybe waitpid(-1, ...)
on that platform will never conflict with mjit use of waitpid.
In any case, I've added WAITPID_USE_SIGCHLD macro to vm_core.h
so it can be easy for Linux/BSD users to test (hopefully!)
win32-compatible code.

* vm_core.h (rb_vm_t): move `rb_execution_context_t::safe_level` to
`rb_vm_t::safe_level_` because `$SAFE` is a process (VM) global state.
* vm_core.h (rb_proc_t): remove `rb_proc_t::safe_level` because `Proc`
objects don't need to keep `$SAFE` at the creation.
Also make `is_from_method` and `is_lambda` as 1 bit fields.
* cont.c (cont_restore_thread): no need to keep `$SAFE` for Continuation.
* eval.c (ruby_cleanup): use `rb_set_safe_level_force()` instead of access
`vm->safe_level_` directly.
* eval_jump.c: End procs `END{}` doesn't keep `$SAFE`.
* proc.c (proc_dup): removed and introduce `rb_proc_dup` in vm.c.
* safe.c (rb_set_safe_level): don't check `$SAFE` 1 -> 0 changes.
* safe.c (safe_setter): use `rb_set_safe_level()`.
* thread.c (rb_thread_safe_level): `Thread#safe_level` returns `$SAFE`.
It should be obsolete.
* transcode.c (load_transcoder_entry): `rb_safe_level()` only returns
0 or 1 so that this check is not needed.
* vm.c (vm_proc_create_from_captured): don't need to keep `$SAFE` for Proc.
* vm.c (rb_proc_create): renamed to `proc_create`.
* vm.c (rb_proc_dup): moved from proc.c.
* vm.c (vm_invoke_proc): do not need to set and restore `$SAFE`
for `Proc#call`.
* vm_eval.c (rb_eval_cmd): rename a local variable to represent clearer
meaning.
* lib/drb/drb.rb: restore `$SAFE`.
* lib/erb.rb: restore `$SAFE`, too.
* test/lib/leakchecker.rb: check `$SAFE == 0` at the end of tests.

* vm_insnhelper.c (vm_opt_binop_dispatch): removed because this function
has several issues for micro-benchmark. Write conditions manually.
The worst point is that we can't control value checking order.
For example, we can assume FIXNUM arithmetic operations are most popular
in Ruby, so that we need to check FIXNUM at first.
* test/ruby/test_optimization.rb: also fix redef bug for LE/GT/GE.

[Feature #14045]
* insns.def (getblockparam, setblockparam): add special access
instructions for block parameters.
getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and
if it is not set this instruction creates a Proc object from
a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
setblockparam is similar to setlocal, but set
VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
* compile.c: use get/setblockparm instead get/setlocal instructions.
Note that they are used for method local block parameters (def m(&b)),
not for block local method parameters (iter{|&b|).
* proc.c (get_local_variable_ptr): creates Proc object for
Binding#local_variable_get/set.
* safe.c (safe_setter): we need to create Proc objects for postponed
block parameters when $SAFE is changed.
* vm_args.c (args_setup_block_parameter): used only for block local blcok
parameters.
* vm_args.c (vm_caller_setup_arg_block): if called with
VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be
a block handler.
* test/ruby/test_optimization.rb: add tests.
* benchmark/bm_vm1_blockparam*: added.

capabilities as rb_hash_aset.

The same hash keys may be loaded from tainted data sources
frequently (e.g. parsing headers from socket or loading
YAML data from a file). If a non-tainted fstring already
exists (because the application expects the hash key),
cache and deduplicate the tainted version in the new
tainted_frozen_strings table.
For non-embedded strings, this also allows sharing with the
underlying malloc-ed data.
* vm_core.h (rb_vm_struct): add tainted_frozen_strings
* vm.c (ruby_vm_destruct): free tainted_frozen_strings
(Init_vm_objects): initialize tainted_frozen_strings
(rb_vm_tfstring_table): accessor for tainted_frozen_strings
* internal.h: declare rb_fstring_existing, rb_vm_tfstring_table
* hash.c (fstring_existing_str): remove (moved to string.c)
(hash_aset_str): use rb_fstring_existing
* string.c (rb_fstring_existing): new, based on fstring_existing_str
(tainted_fstr_update): new
(rb_fstring_existing0): new, based on fstring_existing_str
(rb_tainted_fstring_existing): new, special case for tainted strings
(rb_str_free): delete from tainted_frozen_strings table

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.
