[commit] Application to Generate Intrinsic Functions for gcc for MeP

[Dave Brolley]

Hi,

I've committed two files to the cgen directory: cgen-intrinsics.scm and 
intrinsics.scm. Together they form a cgen application which generates 
code to support builtin intrinsic functions for insns in the MeP 
architecture using information and attributes defined in 
cgen/cpu/mep.cpu (and it's included files). The following files in 
gcc/config/mep are generated by this application:

intrinsics.md -- .md file additions
intrinsics.h -- a pseudo-header intended as documentation of the 
intrinsics functions supported. Not to be #included in any source code
mep-intrin.h -- functions used by gcc to generate code for calls to the 
intrinsic functions.
