Rewrite the pattern matching code in trans. #27050

  1. Rewrite the pattern matching code in trans. 

    The old code was not well structured, difficult to understand,
and buggy.

The new implementation is completely naive, so there may be a slight
runtime performance loss. That said, adding optimizations on top of
a clear and correct implementation seems easier than trying to
fix the old mess.

Fixes issue rust-lang#19064.
