Pull in r227115 from upstream clang trunk (by Ben Langmuir):

  Fix assert instantiating string init of static variable

  ... when the variable's type is a typedef of a ConstantArrayType. Just
  look through the typedef (and any other sugar).  We only use the
  constant array type here to get the element count.

This fixes an assertion failure when building the games/redeclipse port.
