4031ff44bb Per code review:
* Clean up the StatusInfo constructor to construct all members and give
  them reasonable values.
* Get rid of the Vector typedef and make the interface to
  getDirectoryContent use a std::set instead of a std::vector so the dir
  content is sorted.
* Make the getStatusInfo method const and not return a useless boolean.

b378786c97 Implement a simple FIXME: if we are emitting a basic block address that has
already been emitted, we don't have to remember it and deal with it later,
just emit it directly.

3f73c77ace * Merge some win32 ifdefs together
* Get rid of "emitMaybePCRelativeValue", either we want to emit a PC relative
  value or not: drop the maybe BS.  As it turns out, the only places where
  the bool was a variable coming in, the bool was a dynamic constant.

89536fedee Now that we have ghost linkage, we can force resolution of external symbols
immediately instead of lazily.

In this program, for example:

int main() {
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
}

We used to have to go through compilation callback 4 times (once for each
call to printf), now we don't go to it at all.

Thanks to Misha for noticing this, and for adding the initial ghost linkage
patches.

583ea4764c There is no reason to try to materialize the function from bytecode if it
already has been.  This may be a small speedup.

571b490404 If a function is external, do not output a FunctionBlock for the function
AT ALL.  This saves 11 bytes per external function from the bytecode file,
and is also required to make GhostLinkage work.

e87a1360b3 Two minor improvements:
1. Speedup getValueState by having it not consider Arguments.  It's better
    to just add them before we start SCCP'ing.
 2. SCCP can delete the contents of dead blocks.  No really, it's ok!  This
    reduces the size of the IR for subsequent passes, even though
    simplifycfg would do the same job.  In practice, simplifycfg does not
    run until much later than sccp in gccas

bde8da9e43 Substantially refactor the SCCP class into an SCCP pass and an SCCPSolver
class.  The only changes are minor:

 * Do not try to SCCP instructions that return void in the rewrite loop.
   This is silly and fool hardy, wasting a map lookup and adding an entry
   to the map which is never used.
 * If we decide something has an undefined value, rewrite it to undef,
   potentially leading to further simplications.
