Move exception raising to scope_new.
...
Besides that fix bugs that mistakenly calls `raise_error` that emits
code to raise runtime error instead of `codegen_error` that terminates
code generation immediately.

Use type predicate macros instead of mrb_type if possible
...

all `enum mrb_vtype`).

Avoid creating unnecessary empty arrays on splat.
...
But this changes requires `OP_ARYCAT` and `OP_ARYPUSH` to accept `nil`
as their first operand. Alternative VMs (e.g. `mruby/c`) that understand
mruby bytecode need to be updated.

Use new specifiers/modifiers of mrb_vfromat()
...
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a5116789a#4613 ,
so I put it back.

The number of local variables should be less than 1024; fix #4370
...
The `env` stores stack length in a 10 bit field.
See `MRB_ENV_STACK_LEN()` macro.

Avoid keeping pointers from mrb_sym2name_len(); fix #4342
...
The addresses for packed inline symbols reference `mrb->symbuf` that
could be overridden by the later call of `mrb_sym2name_len`. Since
file names in call stack information are kept as symbols, keeping the
address in the C structures could cause problems like #4342 .
This changes small incompatible changes in function prototypes:
* `mrb_parser_get_filename`: return value changed to `mrb_sym`.
* `mrb_debug_get_filename`: add `mrb_state*` as a first argument.
* `mrb_debug_get_line`: ditto.
I believe above functions are almost internal, and no third-party
mrbgem use them.

762f682b80
Allow destructuring in formal arguments.
...
e.g.
```
def m(a,(b,c),d); p [a,b,c,d]; end
m(1,[2,3],4) # => [1,2,3,4]
```
mruby limitation:
Destructured arguments (`b` and `c` in above example) cannot be accessed
from the default expression of optional arguments and keyword arguments,
since actual assignment is done after the evaluation of those default
expressions. Thus:
```
def f(a,(b,c),d=b)
p [a,b,c,d]
end
f(1,[2,3])
```
raises `NoMethodError` for `b` in mruby.
