I tend to agree.  This would allow us to do things like find out
that the variable is read-write while compiling the function that
handles all the static initialization.  Later, while looking at
functions that are not connected with initialization, they'll 
appear to be read-only.

The important part is that cgraph will have to know about which
functions are called from where, and whether or not a function can
possibly be invoked at a time in which a variable hasn't completed
its initialization.  And, possibly, whether we ought to generate
multiple copies of a function -- one with the variable read-only
and one read-write.
