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

set up.

10b5a5c0da Do not emit FunctionBlock blocks for external functions. This shrinks 
bytecode files by about 8 bytes per external function

704cad0375 Make *SURE* to null out the pointer before throwing an exception, otherwise 
the dtor for the BytecodeReader class will try to free it again!

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.
