CALL_EXPR representation changes coming; need patch reviewer(s)

[Sandra Loosemore <sandra at codesourcery dot com>]

Last summer I made changes on the LTO branch to the representation of 
CALL_EXPRs, to store the arguments in the expr itself (making it of variable 
size) rather than in an attached TREE_LIST.  The primary purpose of the change 
was memory savings, but introducing new accessor macros and constructor 
functions also had the side-effect of simplifying a lot of code that builds and 
manipulates call expressions.

Recently, Brooks Moses, Lee Millward, and I have been making a push to get these 
changes merged to mainline; we're getting close to finishing testing and will 
probably have a patch ready by the beginning of next week.  Can we get a 
volunteer or volunteers to commit to reviewing the patch?  It's going to be a 
very large patch since this change affects many parts of the compiler; and 
getting it reviewed in a timely manner will help prevent the changes from 
getting bit-rotted again before they can be committed.

Once the patch is approved, we will probably need to ask for a check-in window 
for the final merge and commit, as described in

Thanks,
