3748147aaf Emit the switch stmt cases in alphabetical order instead of pointer order, 
which is not stable.

e6b90fba4a Addition of a simple two pass scheduler. This version is currently hacked up 
for testing and will require target machine info to do a proper scheduling.
The simple scheduler can be turned on using -sched=simple (defaults
to -sched=none)

b1ab458047 Factor this code out into a few methods. 
Implement the start of global ctor optimization.  It is currently smart
enough to remove the global ctor for cases like this:

struct foo {
  foo() {}
} x;

... saving a bit of startup time for the program.
