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.

This does not check that types match yet, but PPC only has one integer type

This also doesn't have the code to build the resultant dag.

not completely painful to use.  Once we decide a directory has a bytecode
library, we know it this function returns true, no need to scan entire directories.
