c92c0a5935 Prefer using vm_base_ptr rather than cfp->bp
in MJIT implementation.

This allows us to drop cfp->bp by just modifying vm_base_ptr in the
future.

No performance impact:

8dd0fb9039 use cfp->bp more.
cfp->bp was (re-)introduced by Kokubun san, but VM doesn't use it
because I (ko1) want to remove it in a future. But using it make
leave instruction fast because of sp consisntency check.
So now VM uses cfp->bp.

To use cfp->bp, I checked the value and I found that it is not a
"initial value of sp" but a "initial value of ep". Fix this problem
and fix all bp references (this is why bp is renamed to bp_).

a75ae6faa9 Use alloca again instead of malloc and free
by changing interface of `mjit_copy_cache_from_main_thread`.

This is also fixing deadlock introduced by r67299.

4d426e28d2 Resurrect r67287 and r67288
I noticed that r67287 was illegal because memory allocated by `alloca`
was used after the stack is expired.

So I just replaced that with `malloc` and `free` for now.

ddcb40f595 mjit_worker.c: carve out worker-related code
The motivation of this change is to make sure rb_funcall or GC-related
functions are not called on worker-related code. Currently such
functions are used in some places and I believe it's partly because it's
hard to identify which part is called on MJIT worker thread.

Now, mjit.c is safe to use them but we know we need to safely deal with
mjit_compile.c, mjit_worker.c and mjit_internal.h.

cd2eaf2a33 mjit.c: handle memory allocation failure
which was missing in r64033.

Prior to r64033, memory allocation failure had been checked by
TRY_WITH_GC and handled by rb_memerror. But calling rb_memerror on MJIT
worker is problematic since it does EC_JUMP_TAG in the end. Threads
except Ruby's main thread must not use it.

6a4bb345df mjit_compile.c: resurrect local variable stack
This optimization was reverted on r63863, but this commit resurrects the
optimization to skip some sp motions on JIT execution.

tool/ruby_vm/views/_mjit_compile_insn_body.erb: ditto
tool/ruby_vm/views/_mjit_compile_insn.erb: ditto

insns.def: resurrect handles_frame as handles_stack, which was deleted
on r63763.
tool/ruby_vm/models/bare_instructions.rb: ditto

vm_insnhelper.c: prevent moving sp outside insns.def to allow modifying
it by JIT.

7a0a585444 revert r62655 for r63763
r63655 was tightly coupled to handle_frames and some assumptions seems
to have been broken by r63763.

To partially resolve Bug#14892, this reverts the optimization for now. I
want to make MJIT CI happy first and then I'll probably retry r63655 by
partially reverting r63763 for sp changes.

The skipped test is not fixed yet.

d2c6ed6b07 mjit_compile.c: drop catch table handling
The loop for `vm_exce_handle_exception` doesn't trigger `mjit_exec`, so
I don't think this code is no longer needed.

This was needed in development of original version of this JIT, but it
seems not needed from the beginning (r62189) at Ruby repository.

8a15857a7f mjit_compile.c: use local variables for stack
if catch_except_p is FALSE. If catch_except_p is TRUE, stack values
should be on VM's stack when exception is thrown and the JIT-ed frame
is re-executed by VM's exception handler. If it's FALSE, the JIT-ed
frame won't be re-executed and don't need to keep values on VM's stack.

Using local variables allows us to reduce cfp->sp motion. Moving cfp->sp
is needed only for insns whose handles_frame? is false. So it improves
performance.

_mjit_compile_insn.erb: Prepare `stack_size` variable for GET_SP,
STACK_ADDR_FROM_TOP, TOPN macros. Share pc and sp motion partial view.
Use cancel handler created in mjit_compile.c.

_mjit_compile_send.erb: ditto. Also, when iseq->body->catch_except_p is
TRUE, this stops to call mjit_exec directly. I described the reason in
vm_insnhelper.h's comment for EXEC_EC_CFP.

_mjit_compile_pc_and_sp.erb: Shared logic for moving sp and pc. As you
can see from thsi file, when status->local_stack_p is TRUE and
insn.handles_frame? is false, moving sp is skipped. But if
insn.handles_frame? is true, values should be rolled back to VM's stack.
common.mk: add dependency for the file

_mjit_compile_insn_body.erb: Set sp value before canceling JIT on
DISPATCH_ORIGINAL_INSN. Replace GET_SP, STACK_ADDR_FROM_TOP, TOPN macros
for the case ocal_stack_p is TRUE and insn.handles_frame? is false.
In that case, values are not available on VM's stack and those macros
should be replaced.

mjit_compile.inc.erb: updated comments of macros which are supported by
JIT compiler. All references to `cfp->sp` should be replaced and thus
INC_SP, SET_SV, PUSH are no longer supported for now, because they are
not used now.

vm_exec.h: moved EXEC_EC_CFP definition to vm_insnhelper.h because it's
tighly coupled to CALL_METHOD.

vm_insnhelper.h: Have revised EXEC_EC_CFP definition moved from vm_exec.h.
Now it triggers mjit_exec for VM, and has the guard for catch_except_p
on JIT-ed code. See comments for details. CALL_METHOD delegates
triggering mjit_exec to EXEC_EC_CFP.

insns.def: Stopped using EXEC_EC_CFP for the case we don't want to
trigger mjit_exec. Those insns (defineclass, opt_call_c_function) are
not supported by JIT and it's safe to use RESTORE_REGS(), NEXT_INSN().
expandarray is changed to pass GET_SP() to replace the macro in
_mjit_compile_insn_body.erb.

vm_insnhelper.c: change to take sp for the above reason.

[close https://github.com/ruby/ruby/pull/1828]

This patch resurrects the performance which was attached in
[Feature #14235].
