commit 3ae97e5f38e85a5db76053ed2c7757c59a22f73d

    Optimize interpolation
    
    Before, all interpolation was codegenned with a call to "Stringy".  This
    has several disadvantages:
    - it created a more opcodes (this patch makes core setting 25K smaller)
    - it wouldn't allow for better optimized infix:<~> candidates
    - it didn't allow custom infix:<~> to be seen (as all became Str)
    
    This commit does the following things:
    - remove codegenning a method call to Stringy
      - except if it's the only one, to handle the case of "$a".WHAT
    - add several candidates for infix:<~> to handle optimisable cases
      - Cool ~ Str | Str ~ Cool | Cool ~ Cool: directly call Cool.Str
      - str ~ Str | Str ~ str | str ~ str: always return a str
      - [~] @foo: now handles str @foo | @foo with separate candidate
    
    This made code like "$a $a":
    - 2% faster in the case of $a being a Str
    - 10% faster in the case of $a being an Int
    - 2x as fast in the case of $a being a str
