693787a5ec Instcombine: cast (X != 0) to int, cast (X == 1) to int -> X iff X has only the low bit set.
This implements set.ll:test20.

This triggers 2x on povray, 9x on mesa, 11x on gcc, 2x on crafty, 1x on eon,
6x on perlbmk and 11x on m88ksim.

It allows us to compile these two functions into the same code:

struct s { unsigned int bit : 1; };
unsigned foo(struct s *p) {
  if (p->bit)
    return 1;
  else
    return 0;
}
unsigned bar(struct s *p) { return p->bit; }

cea6559f60 Implement the IsDigitOptimization for simplifying calls to the isdigit
library function:
  isdigit(chr) -> 0 or 1 if chr is constant
  isdigit(chr) -> chr - '0' <= 9 otherwise

Although there are many calls to isdigit in llvm-test, most of them are
compiled away by macros leaving only this:

58b563ce43 * Correct the function prototypes for some of the functions to match the
actual spec (int -> uint)
* Add the ability to get/cache the strlen function prototype.
* Make sure generated values are appropriately named for debugging purposes
* Add the SPrintFOptimiation for 4 casts of sprintf optimization:
    sprintf(str,cstr) -> llvm.memcpy(str,cstr) (if cstr has no %)
    sprintf(str,"")   -> store sbyte 0, str
    sprintf(str,"%s",src) -> llvm.memcpy(str,src) (if src is constant)
    sprintf(str,"%c",chr) -> store chr, str   ; store sbyte 0, str+1

The sprintf optimization didn't fire as much as I had hoped:
