81587e798a Checking in Chris's suggestions: 
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

do something dumb, and inefficient, but more complete.

d9f4ffdf5e Get the list of PHI node values before the basic block is split. Also, add 
PHI node entries for unwind instructions just like for call instructions which
became invokes!  This fixes PR57, tested by

0658cc20bd Make this pass substantially stronger by having it delete dead return values 
as well as arguments.  Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead.  This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.

of 3 176.gcc source files (reload1.c, global.c, flow.c)
