and specialized Array#any? and Hash#any?

Traditionally, method coverage measurement was implemented by inserting
`trace2` instruction to the head of method iseq. So, it just measured
methods defined by `def` keyword.
This commit drastically changes the measuring mechanism of method
coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t*
to runs (i.e., it counts the runs per method entry), and at
`Coverage.result`, it creates the result hash by enumerating all
`rb_method_entry_t*` objects (by `ObjectSpace.each_object`).

Sometimes, size of a hash can be calcluated a priori. By providing
such info to the constructor we can avoid unnecessary internal re-
allocations. This can boost for instance creation of hash literals.

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.

In typical applications, hash entries are read after being
written to. Blindly writing to hashes which are never read
makes little sense. So, for any hash which is read from, an
fstring entry for the key should already exist for the key.
We no longer blindly create fstrings if the code is blindly
setting random hash keys, preventing the performance regression
in the reverted r43870.
Regarding <https://bugs.ruby-lang.org/issues/9188>, this has a
minimum impact on the bm_so_k_nucleotide where hash keys are set
and not reused, performance is within 1-2% of existing cases.
* hash.c: #include gc.h for rb_objspace_garbage_object_p
(hash_aset_str): do read-only check of fstring table and
reuse fstring if it exists and is still alive (not garbage)

To convert the object implicitly, it has had two parts in convert_type() which are
1. lookink up the method's id
2. calling the method
Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up
the method's id for type conversion.
This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id)
to call the method without looking up the method's id when convert the object.

Same as rb_ary_tmp_new_from_values(), it reduces vm_exec_core binary
size from 26,176 bytes to 26,080 bytes. But this time, also with a
bit of optimizations:
- Because we are allocating a new hash and no back references are
introduced at all, we can safely skip write barriers.
- Also, the iteration never recurs. We can avoid complicated
function callbacks by using st_insert instead of st_update.

Patch by Eric Wong [ruby-core:78797].
I don't like the idea of making insns.def any bigger to support
a corner case, and "test_hash_aref_fstring_identity" shows
how contrived this is.

* hash.c (prime1, prime2): split long long literals for platforms
where LL suffix is not supported, e.g., VC6.

The same code is used for has_value? and value?, but according to
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/43765
has_value is deprecated. Use the non-deprecated syntax in the examples.

* hash.c (any_hash): should return `long', because ruby assumes
the hash value of the object id of an object is `long'.
