[fixed-point] Fixed-point branch merge plan

Hi, As Mark requested, we propose a merge plan for the fixed-point branch as follows. 1. Merge in machine modes to support signed and unsigned fract and accum modes. Handle scalar and vector modes. 2. Merge in fixed-value.h and fixed-value.c to handle fixed-point values. 3. Merge in TREE

Fixed-point branch?

Joseph, Richard -- As C maintainers, have either of you looked at Chao-Ying's fixed-point branch? My understanding (from the note on the Wiki page) is that the fixed-point support is now in reasonably good shape, and works on all architectures, using an emulation library. So, I'm wo
