For now, we translate linkonce into weak linkage in the bytecode format because

Completely rewrite support for the Value::use_* list.  Now, all operations on
this list (except use_size()) are constant time.  Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.

This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:

176.gcc:     77.07s -> 37.38s

Output a contorted sequence of instructions to make sure that we don't access
off the bottom of the stack.  This fixes PR#41

Disable the leaf function optimization, which is apparently not legal on
X86/linux.  :(  The problem is that a signal delivered while the function
is executing could clobber the functions stack.  This is a partial fix
for PR41.

Added a link to the main page for LLVM.
Made the "Submitting a Bug" reference point to the web site, as we want people
