eliminating the @'s from them when used on func's. This is progress towards
<rdar://problem/17527000> change operator declarations from "operator prefix" to "prefix operator" & make operator a keyword
This also consolidates rejection of custom operator definitions into one
place and makes it consistent, and adds postfix "?" to the list of rejected
operators.
This also changes the demangler to demangle weak/inout/postfix and related things
without the @.

Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able." Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.
There are obvious improvements to make in some of these names, which can
be handled with separate commits.
Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.

Reimplement 'switch' parsing for our new AST representation, where cases contain patterns and 'where' guards, case blocks can have multiple cases, and 'default' is constrained to being the lone label of the last block if present. No type-checking or parsing of actual pattern productions yet.
Swift SVN r5834
Implement switch statements with simple value comparison to get the drudge work of parsing and generating switches in place. Cases are checked using a '=~' operator to compare the subject of the switch to the value in the case. Unlike a C switch, cases each have their own scope and don't fall through. 'break' and 'continue' apply to an outer loop rather to the switch itself. Multiple case values can be specified in a comma-separated list, as in 'case 1, 2, 3, 4:'. Currently no effort is made to check for duplicate cases or to rank cases by match strength; cases are just checked in source order, and the first one wins (aside from 'default', which is branched to if all cases fail).
