* string.c (str_duplicate): share the root shared string if the
original string is already sharing, so that all shared strings
refer the root shared string directly. indirect sharing can
cause a dangling pointer.

The modern Georgian script is special in that it has an 'uppercase'
variant called MTAVRULI which can be used for emphasis of whole words,
for screamy headlines, and so on. However, in contrast to all other
bicameral scripts, there is no usage of capitalizing the first letter
in a word or a sentence. Words with mixed capitalization are not used
at all.
We therefore implement special behavior for String#capitalize. Formally,
we define String#capitalize as first applying String#downcase for the
whole string, then using titlecase on the first letter. Because Georgian
defines titlecase as the identity function both for MTAVRULI ('uppercase')
and Mkhedruli (lowercase), this results in String#capitalize being
equivalent to String#downcase for Georgian. This avoids undesirable
mixed case.
* enc/unicode.c: Actual implementation
* string.c: Add mention of this special case for documentation
* test/ruby/enc/test_case_mapping.rb: Add two tests, a general one
that uses String#capitalize on some (including nonsensical)
combinations of MTAVRULI and Mkhedruli, and a canary test to
detect the potential assignment of characters to the currently
open slots (holes) at U+1CBB and U+1CBC.
* test/ruby/enc/test_case_comprehensive.rb: Tweak generation of
expectation data.
Together with r65933, this closes issue #14839.

It seems that decades ago, ruby was written under assumption that
char is unsigned. Which is of course a false assumption. We
need to explicitly store a numeric value into an unsigned char
variable to tell we expect 0..255 value.

The behaviour of String#setbyte has been depending on the width
of int, which is not portable. Must check explicitly.

Looking at the lines right above, it is clear than a blue sky
that we cannot assume `p` to be aligned at all when
UNALIGNED_WORD_ACCESS is true. It is a wrong idea to use
__builtin_assume_aligned for that situation.

* transient_heap.c, transient_heap.h: implement TransientHeap (theap).
theap is designed for Ruby's object system. theap is like Eden heap
on generational GC terminology. theap allocation is very fast because
it only needs to bump up pointer and deallocation is also fast because
we don't do anything. However we need to evacuate (Copy GC terminology)
if theap memory is long-lived. Evacuation logic is needed for each type.
See [Bug #14858] for details.
* array.c: Now, theap for T_ARRAY is supported.
ary_heap_alloc() tries to allocate memory area from theap. If this trial
sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on.
We don't need to free theap ptr.
* ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that
if ary is allocated at theap, force evacuation to malloc'ed memory.
It makes programs slow, but very compatible with current code because
theap memory can be evacuated (theap memory will be recycled).
If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT()
instead of RARRAY_CONST_PTR(). If you can't understand when evacuation
will occur, use RARRAY_CONST_PTR().
