Yukihiro "Matz" Matsumoto c310c8dc24 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.

Yukihiro "Matz" Matsumoto ec6c8b2a3c Add local variable reordering to kwargs; ref #4746 2019-10-03 09:17:37 +09:00
Yukihiro "Matz" Matsumoto 47cdda370e Need to reorder local variables defined in opt; fix #4746 
For example, local variables in the following def:
```ruby
def foo(a = (not_set = true), &block)
  ...
end
```
should be `a, block, not_set`, but were `a, not_set, block`.

Yukihiro "Matz" Matsumoto 06c7ff0666 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.

Ryan Lopopolo eeb7d3a04f Support parsing a Regexp literal with 'o' option 
CRuby supports a 'o' `Regexp` option for `Regexp` literals, e.g. `/foo/o` that disables multiple interpolation passes.

This commit adds support for parsing such literals. Nothing is done with the option, it is consumed and ignored by the parser.

Yukihiro "Matz" Matsumoto 9b604abc83 Enable YYSTACK_USE_ALLOCA. 
It used heap allocated memory for the parser stack, but there's
possibility of parser termination by exceptions. In that case, the
parser stack memory is leaked.

We were afraid of stack consumption, but parser stack size is only 4KB,
so we don't have to worry about it (at least for the parser).
