78771c886a Fix bug: test/Regression/CBackend/2002-05-16-NameCollide.ll by tracking
which global variables would have name collisions if they were not mangled,
and use this info to mangle them iff they would collide.

3af3ba8b38 Last minor cleanups, this code still does not work for all cases, but it
works much better than it used to.

d0c668c380 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).

4fbf26d2fc * Remove CInstPrintVisitor class, incorporating it into the CWriter class
* Reorder code in the file to make it more logically laid out.

497e19aee0 Remove CLocalVars data structure entirely, instead of building stuff and
then printing it out, just print as we go.

1f02c8910a * 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

8c8a37061a Emit:
l3_reg109 = l81_this->field0;
Instead of:
  l3_reg109 = l81_this[0u].field0;

where possible

8c3c4bfcfe * Print structures types correctly
* Clean up generated code to not emit basic block labels and goto
  instructions if they are unneccesary (for example, fall throughs)

deed7a5ae3 * Continue cleanup of type printing code
* Print a newline after a malloc instruction
* Convert unprintable characters to x_ instead of _x so that we don't
  generate identifiers that start with underscores

2d05a1acb0 * 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.

2f49902374 Simplify and clean up function calls.
Now indirect function calls work, except that function pointer types are not correct.

2f5eb4e9a5 * Remove dead function
* Print C strings correctly
* Expand C escape sequences nicely (ie \n \t, etc get generated instead of hex escapes)

2f5f51a852 Many random fixes:
* Use binary operator logic for shifts instead of cloning code
 * Unary not is '~' not '!'

f34ee81c5e Incorporate and purge function before and after printing them so unnamed values
have some hope of working right.

Function calls do not try to emit an lvalue if they return void.

b5af06a0ec Factor out the code to print a value to ONE place.
It turns out that unnamed values DO NOT work at all, that's next on the list.
