Method name get_how_p_p_p is leaking to user-lever error message along with some weird (my code is one-liner) line number 158519259.

$ perl6 -e 'class A{}; Any.HOW(A).WHAT.say'
use of uninitialized value of type Mu in string context in any <anon> at src/gen/BOOTSTRAP.pm​:104

use of uninitialized value of type Mu in string context in any <anon> at src/gen/BOOTSTRAP.pm​:104

===SORRY!===
error​:imcc​:The opcode 'get_how_p_p_p' (get_how<3>) was not found. Check the type and number of the arguments
  in file '(file unknown)' line 158519259

Yeah, we should catch that bogus syntax rather earlier :)

It's now more informative​:

class A{}; Any.HOW(A).WHAT.say
Cannot give arguments to HOW

I added the exception type X​::Syntax​::Argument​::MOPMacro, so should be
easy to add tests.

Tagging testneeded.

The RT System itself - Status changed from 'new' to 'open'
