SIL Parser: parse protocol_method.

New format for SILConstant:
  '#' sil-dotted-path sil-constant-kind-and-uncurry-level?
  sil-dotted-path:
    identifier ('.' identifier)*
  sil-constant-kind-and-uncurry-level:
    '!' sil-constant-kind ('.' sil-constant-uncurry-level)? ('.objc')?
    '!' sil-constant-uncurry-level ('.objc')?
    '!objc'
  sil-constant-kind:
    'func' | 'getter' | 'setter' | 'allocator' | 'initializer' | 'oneofelt' \
    | 'destroyer' | 'globalaccessor'

Add helper function printFullContext in SILPrinter to generate the fully
qualified dotted path for a given DeclContext; Add parseSILConstant to
SILParser; Testing cases are updated to reflect the new format.
