memory leak in ssa-ccp.c

[Dan Nicolaescu]

ssa_edges is allocated but never freed.


The patch compiles on sparc-sun-solaris2.8

Trying ssa-ccp on Preston Briggs' Optimizer Evaluation code 
at ftp://ftp.cs.rice.edu/public/preston/eval
specifically ftp://ftp.cs.rice.edu/public/preston/eval/cprop.c

crashes the compiler (segmentation fault) on both sparc and x86-linux
with or without this patch...
