590bcc9629 We actually need this code for the release build to prevent link errors,
un#ifdef it.

0671b3db5d * Add support for the -stats command line option to report how much is changed
* Make cast-of-self-ty DCE the dead cast instruction immediately instead of
  waiting for it to be DCE'd by another sweep over the function.  This speeds
  this up noticably.

a98304f4fa Last minor cleanups, this code still does not work for all cases, but it
works much better than it used to.

4ece8deba5 Two Cleanups to generated C code:
1. Avoid printing *(&globalvariable), instead print globalvariable alone
   as a special case.
2. Inline subexpressions into expressions as much as legal that preserves
   execution characteristics of expressions.  Now we get nice (but
   over-parenthesized, oh well) things like:

     ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream));

   instead of five seperate instructions (bsBuff & bsStream are globals).

3fd3c03371 Remove CLocalVars data structure entirely, instead of building stuff and
then printing it out, just print as we go.

aa1d35be51 * Clean up how PHI nodes are handled
* Correct global variable references
* Fix loads & stores with zero indices
* Do not emit an else part of a branch if there is no code (no phi node
  and a fallthrough branch), makes code more readable to get:
  if (l2_cond240) {
    goto l13_bb10;
  }

with no else{} branch

619c55baec * Remove dead "constant printing" code
* Mangle names with only a prefix so that they are easier on the eyes.
* Put spaces around binary operators with low precedence to make them easier to read
* Don't prefix function names with &, although it's correct, it's unnecesary and
  easier to read without it.

87d656d2a6 Incorporate and purge function before and after printing them so unnamed values
have some hope of working right.
