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.

52da956231 * Make sure the string table gets read even if there isn't a foreign 
symbol table.
* Make sure we update the file pointer for each member when rebuilding the
  symbol table.
