Provide better way to check compile errors.

Now you can just call `mrb_load_*` functions then check
`context->parser_nerr > 0` if the return value is `undef`,
instead of calling `mrb_parse_*` functions independently.

Fixed OP_RESCUE code generation bug; fix #3519
...
916b8e let code executed with mrb->exc set, and may cause a crash
like #3519 . Instead modified OP_RESCUE again. To retrieve the exception
object, we use `OP_RESCUE R(A), 0, 0` (old behavior). To compare the
exception object and the class, we use `OP_RESCUE R(A), R(B), 1`.
The reason we use OP_RESCUE for two instruction switched by operand
C is to save the instruction space.
As a result, the following code:
```ruby
begin
raise "a"
rescue TypeError
p 1
rescue RuntimeError
p 2
end
```
will be compiled as:
```
irep 0x55cd1f565cb0 nregs=4 nlocals=1 pools=1 syms=4 reps=0
file: -
2 000 OP_ONERR 005
2 001 OP_LOADSELF R1
2 002 OP_STRING R2 L(0) ; "a"
2 003 OP_SEND R1 :raise 1

Generate new OP_RESCUE; fix #3487
...
The old OP_RESCUE took one operand A, which specifies a class
to match with the exception. The new OP_RESCUE takes tree operands:
A: the register to hold exception
B: the matching exception; the match result will be stored here.
C: the continuation; if C is zero, the exception will be stored to R(A)
otherwise, the value from R(A) is used as a exception.
Thus,
```ruby
begin
raise "a"
rescue TypeError
p 1
rescue RuntimeError
p 2
end
```
will be compiled as
```
irep 0x557a06667aa0 nregs=4 nlocals=1 pools=1 syms=4 reps=0
file: /tmp/e.rb
2 000 OP_ONERR 005

2 003 OP_SEND R1 :raise 1

3 005 OP_GETCONST R2 :TypeError
3 006 OP_RESCUE R1 R2
3 007 OP_JMPIF R2 009
3 008 OP_JMP 013
4 009 OP_LOADSELF R1
4 010 OP_LOADI R2 1
4 011 OP_SEND R1 :p 1
4 012 OP_JMP 023
5 013 OP_GETCONST R2 :RuntimeError
5 014 OP_RESCUE R1 R2 cont
5 015 OP_JMPIF R2 017
5 016 OP_JMP 021
6 017 OP_LOADSELF R1
6 018 OP_LOADI R2 2
6 019 OP_SEND R1 :p 1
6 020 OP_JMP 023
6 021 OP_RAISE R1
6 022 OP_POPERR 1
6 023 OP_STOP
```
The new VM can accept old OP_RESCUE. The mruby compatible VM (namely
mruby/c) should be updated to support the new OP_RESCUE behavior.
