Use of uninitialized value fixed

TParseContext::addConstVectorNode() was returning a
TIntermTyped* variable of the wrong type if a swizzle
was of a different size than the vector's size. When
parseVectorFields() fails, fields.num is reset to 1,
which no longer matches fieldString.size(), so
fieldString.size() should not have been used. To
avoid future errors, the proper type is now set
directly within TParseContext::addConstVectorNode().
