93fb65370c * 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

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.

e8573f21c7 Simplify and clean up function calls.
Now indirect function calls work, except that function pointer types are not correct.

87d656d2a6 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.

80f7e2db14 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.
