2.5's line coverage measurement was about two times slower than 2.4
because of two reasons; (1) vm_trace uses rb_iseq_event_flags (which
takes O(n) currently where n is the length of iseq) to get an event
type, and (2) RUBY_EVENT_LINE uses setjmp to call an event hook.
This change adds a special event for line coverage,
RUBY_EVENT_COVERAGE_LINE, and adds `tracecoverage` instructions where
the event occurs in iseq.
`tracecoverage` instruction calls an event hook without vm_trace.
And, RUBY_EVENT_COVERAGE_LINE is an internal event which does not
use setjmp.
This change also cancells lineno change due to the deletion of trace
instructions [Feature #14104]. So fixes [Bug #14191].

hooks are enabled.
* iseq.c (rb_iseq_trace_set): added to toggle `trace_` instructions.

This function is a body of `trace_` prefix instructions.

Surprisingly, it doesn't use `th` (now `ec`) so this patch is for
the future extension.

to represent execution context [Feature #14038]
* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
There are many code using `th` to represent execution context
(such as cfp, VM stack and so on). To access `ec`, they need to
use `th->ec->...` (adding one indirection) so that we need to
replace them by passing `ec` instead of `th`.
* vm_core.h (GET_EC()): introduced to access current ec. Also
remove `ruby_current_thread` global variable.
* cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of
rb_context_t::thread_value.
* cont.c (ec_set_vm_stack): added to update vm_stack explicitly.
* cont.c (ec_switch): added to switch ec explicitly.

[Feature #14045]
* insns.def (getblockparam, setblockparam): add special access
instructions for block parameters.
getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and
if it is not set this instruction creates a Proc object from
a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
setblockparam is similar to setlocal, but set
VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM.
* compile.c: use get/setblockparm instead get/setlocal instructions.
Note that they are used for method local block parameters (def m(&b)),
not for block local method parameters (iter{|&b|).
* proc.c (get_local_variable_ptr): creates Proc object for
Binding#local_variable_get/set.
* safe.c (safe_setter): we need to create Proc objects for postponed
block parameters when $SAFE is changed.
* vm_args.c (args_setup_block_parameter): used only for block local blcok
parameters.
* vm_args.c (vm_caller_setup_arg_block): if called with
VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be
a block handler.
* test/ruby/test_optimization.rb: add tests.
* benchmark/bm_vm1_blockparam*: added.

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.

into a hash. Given arguments are first inserted into the

This arrangement (rb_ prefixed function placed in st.c) is
unavoidable because it both touches table internal and write
barrier at once.

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.

Contemporary C compilers are good at function inlining. They fold
multiple functions into one. However they are not yet smart enough to
unfold a function into several ones. So generally speaking, it is
wiser for a C programmer to manually split C functions whenever
possible. That should make rooms for compilers to optimize at will.
Before this changeset insns.def was converted into single HUGE
function called vm_exec_core(). By moving each instruction's core
into individual functions, generated C source code is reduced from
3,428 lines to 2,847 lines. Looking at the generated assembly
however, it seems my compiler (gcc 6.2) is extraordinary smart so that
it inlines almost all functions I introduced in this changeset back
into that vm_exec_core. On my machine compiled machine binary of the
function does not shrink very much in size (28,432 bytes to 26,816
bytes, according to nm(1)).
I believe this change is zero-cost. Several benchmarks I exercised
showed no significant difference beyond error mergin. For instance
3 repeated runs of optcarrot benchmark on my machine resulted in:
before this: 28.330329285707490, 27.513378371065920, 29.40420215754537
after this: 27.107195867280414, 25.549324021385907, 30.31581919050884
in fps (greater==faster).

Looking at the source code, FIXABLE tends to be just before LOING2FIX
to check applicability of that operation. Why not try computing first
then check for overflow, which should be optimial.
I also tried the same thing for unsigned types but resulted in slower
execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs.

NOTE:
(1) Fixnum's LSB is always 1.
It means you can always run `x - 1` without overflow.
(2) Of course `z = x + (y-1)` may overflow.
Now z's LSB is always 1, and the MSB of true result is also 1.
You can get true result in long as `(1<<63)|(z>>1)`,
and it equals to `(z<<63)|(z>>1)` == `ror(z)`.
GCC and Clang have __builtin_add_ovewflow:

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.
