[Fixed Point Arithmetic] Addition of the remaining fixed point types and their saturated equivalents This diff includes changes for the remaining _Fract and _Sat fixed point types. ``` signed short _Fract s_short_fract; signed _Fract s_fract; signed long _Fract s_long_fract; unsigned short _Fract u_short_fract; unsigned _Fract u_fract; unsigned long _Fract u_long_fract; // Aliased fixed point types short _Accum short_accum; _Accum accum; long _Accum long_accum; short _Fract short_fract; _Fract fract; long _Fract long_fract; // Saturated fixed point types _Sat signed short _Accum sat_s_short_accum; _Sat signed _Accum sat_s_accum; _Sat signed long _Accum sat_s_long_accum; _Sat unsigned short _Accum sat_u_short_accum; _Sat unsigned _Accum sat_u_accum; _Sat unsigned long _Accum sat_u_long_accum; _Sat signed short _Fract sat_s_short_fract; _Sat signed _Fract sat_s_fract; _Sat signed long _Fract sat_s_long_fract; _Sat unsigned short _Fract sat_u_short_fract; _Sat unsigned _Fract sat_u_fract; _Sat unsigned long _Fract sat_u_long_fract; // Aliased saturated fixed point types _Sat short _Accum sat_short_accum; _Sat _Accum sat_accum; _Sat long _Accum sat_long_accum; _Sat short _Fract sat_short_fract; _Sat _Fract sat_fract; _Sat long _Fract sat_long_fract; ``` This diff only allows for declaration of these fixed point types.

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. Fixed the test that was failing by not checking for dso_local on some targets. Differential Revision: https://reviews.llvm.org/D46084 llvm-svn: 333923

[Fixed Point Arithmetic] Fix for bug where integer literals could be treated as fixed point literals This addresses a bug brought up in https://bugs.llvm.org/show_bug.cgi?id=38161 where integer literals could be treated as fixed point types and throw errors related to fixed point types when the 'k' or 'r' suffix used. The fix also addresses the second issue brought up with the assertion by not treating integers as fixed point types in the first place. Integers that have suffixes 'k' and 'r' now throw the error `invalid suffix 'k/r' on integer constant`. A few more tests were also added to ensure that fixed point types, and any errors/warnings related to them, are limited to C for now. Prior discussion also at https://reviews.llvm.org/D46915.
