in debugflags, as requested by nobu
I actually wanted to check debugflags directly rather than MJIT_DEBUGFLAGS
because debugflags is always used but MJIT_DEBUGFLAGS may not be always used.
But I couldn't find a better way to check debugflags.

This is necessary to avoid converting a hard tab to just 1 space in
preprocessor to generate rb_mjit_header.h, which is helpful when using
gdb or perf report.

This patch contains several ideas:
(1) Disposable inline method cache (IMC) for race-free inline method cache
* Making call-cache (CC) as a RVALUE (GC target object) and allocate new
CC on cache miss.
* This technique allows race-free access from parallel processing
elements like RCU.
(2) Introduce per-Class method cache (pCMC)
* Instead of fixed-size global method cache (GMC), pCMC allows flexible
cache size.
* Caching CCs reduces CC allocation and allow sharing CC's fast-path
between same call-info (CI) call-sites.
(3) Invalidate an inline method cache by invalidating corresponding method
entries (MEs)
* Instead of using class serials, we set "invalidated" flag for method
entry itself to represent cache invalidation.
* Compare with using class serials, the impact of method modification
(add/overwrite/delete) is small.
* Updating class serials invalidate all method caches of the class and
sub-classes.
* Proposed approach only invalidate the method cache of only one ME.
See [Feature #16614] for more details.

Now, rb_call_info contains how to call the method with tuple of
(mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and
mid+argc+flags only requires 64bits. So this patch packed
rb_call_info to VALUE (1 word) on such cases. If we can not
represent it in VALUE, then use imemo_callinfo which contains
conventional callinfo (rb_callinfo, renamed from rb_call_info).
iseq->body->ci_kw_size is removed because all of callinfo is VALUE
size (packed ci or a pointer to imemo_callinfo).
To access ci information, we need to use these functions:
vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci).
struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg.
rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc()
is temporary removed because cd->ci should be marked.

On cross-compilation, compiled binary can no be created because
compiled binary should be created by same interpreter (on cross-
compilation, host ruby is used to build ruby (BASERUBY)).
So that cross-compilation system loads required scripts in text.
It is same as miniruby.

prelude.c is an automatically generated file by template/prelude.c.tmpl.
However it does not contain any required functions. So remove it from
dependency.
Also miniprelude.c is included by mini_builtin.c and does not need
to make miniprelude.o.

vm_getivar() provides fastpath for T_OBJECT by caching an index
of ivar. This patch also provides fastpath for FL_EXIVAR objects.
FL_EXIVAR objects have an each ivar array and index can be cached
as T_OBJECT. To access this ivar array, generic_iv_tbl is exposed
by rb_ivar_generic_ivtbl() (declared in variable.h which is newly
introduced).
Benchmark script:
Benchmark.driver(repeat_count: 3){|x|
x.executable name: 'clean', command: %w'../clean/miniruby'
x.executable name: 'trunk', command: %w'./miniruby'
objs = [Object.new, 'str', {a: 1, b: 2}, [1, 2]]
objs.each.with_index{|obj, i|
rep = obj.inspect
rep = 'Object.new' if /\#/ =~ rep
x.prelude str = %Q{
v#{i} = #{rep}
def v#{i}.foo
@iv # ivar access method (attr_reader)
end
v#{i}.instance_variable_set(:@iv, :iv)
}
puts str
x.report %Q{
v#{i}.foo
}
}
}
Result:
v0.foo # T_OBJECT
