Not only TRACE_ELEMENT but also INSN_ELEMENT may have events.
The old pc2branchindex was created using only events of TRACE_ELEMENTs.
This change uses events of INSN_ELEMENTs too for pc2branchindex table.

Previously, these hash literals were not frozen, and thus could be
modified by ObjectSpace, resulting in undesired behavior. Example:
```ruby
require 'objspace'
def a(b={0=>1,1=>4,2=>17})
b
end
p a
ObjectSpace.each_object(Hash) do |a|
a[3] = 8 if a.class == Hash && a[0] == 1 && a[1] == 4 && a[2] == 17
end
p a
```
It may be desirable to hide such hashes from ObjectSpace, since
they are internal, but I'm not sure how to do that.

`code_index` doesn't need to be incremented since the mark array has
been removed. Thanks for the patch ko1!

* compile.c (ibf_load_iseq_each): iseq_mark assumes that if
param.flags.has_kw is TRUE, then param.keyword is not NULL.
To confirm this assumption, make it FALSE before param.keyword
is initialized.

The coverage counters is initialized with `counter[lineno - 1] = 0`,
but lineno may be 0, which led to write access for index -1.

The instructions are just for optimization. To clarity the intention,
this change adds the prefix "opt_", like "opt_case_dispatch".

When loading iseq from binary while a TracePoint is on, we need to
recompile instructions to their "trace_" variant. Before this commit
we only recompiled instructions in the top level iseq, which meant
that TracePoint was malfunctioning for code inside module/class/method
definitions.
* compile.c: Move rb_iseq_init_trace to rb_ibf_load_iseq_complete.
It is called on all iseqs during loading.
* test_iseq.rb: Test that tracepoints fire within children iseq when
using load_from_binary.

* hash.c, internal.h: support theap for small Hash.
Introduce RHASH_ARRAY (li_table) besides st_table and small Hash
(<=8 entries) are managed by an array data structure.
This array data can be managed by theap.
If st_table is needed, then converting array data to st_table data.
For st_table using code, we prepare "stlike" APIs which accepts hash value
and are very similar to st_ APIs.
This work is based on the GSoC achievement

* 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().
