When generate Hash object, the heap area of st_table will be always allocated in internally
and seems it take a time.
To improve performance of creating Hash object,
this patch will reduce count of allocating heap areas for st_table by reuse them.
Performance of creating Hash literal -> 1.53 times faster.

* st.c (rb_hash_bulk_insert): new API to bulk insert entries
into a hash. Given arguments are first inserted into the
table at once, then reindexed. This is faster than inserting
things using rb_hash_aset() one by one.
This arrangement (rb_ prefixed function placed in st.c) is
unavoidable because it both touches table internal and write
barrier at once.

Previous implementation had an issues:
- macros murmur1 assumes murmur_step takes rotation value
as a second argument
- but murmur_step second argument is "next block"
- this makes st_hash_uint and st_hash_end to not mix high bits of
hash value into lower bits
- this leads to pure hash behavior on doubles and mixing hashes using
st_hash_uint.
It didn't matter when bins amount were prime numbers, but it hurts
when bins are powers of two.
Mistake were created cause of attempt to co-exist Murmur1 and Murmur2
in a same code.
Change it to single hash-function implementation.
- block function is in a spirit of Murmur functions,
but handles inter-block dependency a bit better (imho).
- final block is read in bit more optimal way on CPU with unaligned word access,
- final block is mixed in simple way,
- finalizer is taken from MurmurHash3 (it makes most of magic :) )
(64bit finalizer is taken from
http://zimbry.blogspot.ru/2011/09/better-bit-mixing-improving-on.html)
Also remove ST_USE_FNV1: it lacks implementation of many functions,
and looks to be abandoned

From: Vladimir Makarov <vmakarov@redhat.com>
By Vladimir's estimation, this requires at least 64 GB of memory
to reproduce this bug due to the hash sizes required. So there
is no new test case (and I am unable to test it, myself).

[Feature #12142]

You can see all of code history here:
<https://github.com/vnmakarov/ruby/tree/hash_tables_with_open_addressing>
This improvement is discussed at
<https://bugs.ruby-lang.org/issues/12142>

and define CONSTFUNC and PUREFUNC if available.
Note that I don't add those options as default because
it still shows many false-positive (it seems not to consider
longjmp).
* vm_eval.c (stack_check): get rb_thread_t* as an argument
to avoid duplicate call of GET_THREAD().

I suspect the build failures with r51034 ("st.c: use ccan linked-list")
on ko1's CI machine was due to me forgetting to update common.mk :x
Lets see what happens when I only include ccan/list/list.h
Will followup with appropriate reverts or reinstating the
rest of r51034 along with a common.mk update as I watch CI
build.

Reduces object size slightly on x86-64:
text data bss dec hex filename
2782359 22400 71880 2876639 2be4df ruby.orig
2781831 22400 71880 2876111 2be2cf ruby.pow2
And on 32-bit x86:
text data bss dec hex filename
2814751 12100 30552 2857403 2b99bb ruby.orig
2814051 12100 30552 2856703 2b96ff ruby.pow2
This is not a performance-critical function, but the
smaller icache footprint seems worth it.
