With ASAN, `EC_TMPPOP_TAG`/`EC_REPUSH_TAG` doesn't work
so rewrite it without them. They are used for the performance,
but here calling stacked `END{}` and not so performance critical.
We can check the function pointer passed to rb_define_global_function
like we do so in rb_define_method. It turns out that almost anybody
is misunderstanding the API.
* 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 `$SAFE == 0` at the end of tests.
* test/rubygems/test_gem.rb: do not set `$SAFE = 1`.
* bootstraptest/test_proc.rb: catch up this change.

to represent execution context [Feature #14038]
* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
There are many code using `th` to represent execution context
(such as cfp, VM stack and so on). To access `ec`, they need to
use `th->ec->...` (adding one indirection) so that we need to
replace them by passing `ec` instead of `th`.
* vm_core.h (GET_EC()): introduced to access current ec. Also
remove `ruby_current_thread` global variable.
* cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of
rb_context_t::thread_value.
* cont.c (ec_set_vm_stack): added to update vm_stack explicitly.
* cont.c (ec_switch): added to switch ec explicitly.
* cont.c (rb_fiber_close): added to terminate fibers explicitly.

Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.
Some code used "status" instead of "state". To make them clear,
rename them to state.
We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

* vm_insnhelper.c (vm_yield_with_cfunc): vm_yield_with_cfunc receives
blockptr and passes it to iterating block.
* proc.c (rb_proc_call), include/ruby/intern.h: rb_proc_call receives
blockptr. "rb_proc_call(self, args, blockptr)" in C corresponds to
"self.call(*args, &block)" in Ruby.
* proc.c (proc_call): pass blockptr to block that is written in C.
* proc.c (curry): receive blockptr and pass it to original proc.
[ruby-core:15551]
