[PATCH] D46084: Addition of the Fixed Point _Accum type

[Leonard Chan via Phabricator via cfe-commits]

leonardchan added a project: clang.

This diff includes changes for supporting the following types.

  // Primary fixed point types
  signed short _Accum s_short_accum;
  signed _Accum s_accum;
  signed long _Accum s_long_accum;
  unsigned short _Accum u_short_accum;
  unsigned _Accum u_accum;
  unsigned long _Accum u_long_accum;
  
  // Aliased fixed point types
  short _Accum short_accum;
  _Accum accum;
  long _Accum long_accum;

This diff only allows for declaration of the fixed point types. Assignment and other operations done on fixed point types according to http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1169.pdf will be added in future patches. The saturated versions of these types and the equivalent `_Fract` types will also be added in future patches.

The tests included are for asserting that we can declare these types.
