0752044e03 Fix output of typedefs to avoid syntax errors. 
* We now can correctly Cify the Olden-power benchmark

1c1de51dfe * Add a couple of comments to the output c code 
* _FIX_ infinite recursion problem, due to typedefs of a structure being
  printed before the structure.

af6a9e8fc4 Another change that doesn't affect functionality. Since we are only looking 
at types in the symbol table, only traverse the type plane, saving a loop nest.

fa9dd5dba9 Don't print global variable definitions twice! Sun's pathetic compiler

012667a925 No longer need to sign-extend array indices to 64 bits since they 
are now longs and not unsigned ints.

9369cfea20 Fix the way parens are printed around "*ptrName" so that 
no parens are printed around  *, **, ... alone, except if
it is a pointer type for which no name should be printed,
as in the result of a cast.

fc62e1bdb1 - Change constant printing to be better integrated with the rest of the 
CWriter class.  Write directly to stream instead of building a big
      string, then writing it out.

4d98351cea Fix bug: test/Regression/CBackend/2002-05-16-NameCollide.ll by tracking

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).

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

where possible

93fb65370c * Continue cleanup of type printing code

  generate identifiers that start with underscores

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.
