f6d1d7d2ba Remove debugging printout
Instcombine (setcc (truncate X), C1).

This occurs THOUSANDS of times in many benchmarks.  Particularlly common
seem to be things like (seteq (cast bool X to int), int 0)

This turns it into (seteq bool %X, false), which then becomes (not %X).

a41fc77ae4 To go along with sabre's improved InstCombining, improve recognition of
integers that we can use as immediate values in instructions.

Example from yacr2:
-       lis r10, -1
-       ori r10, r10, 65535
-       add r28, r28, r10
+       addi r28, r28, -1
        addi r7, r7, 1
        addi r9, r9, 1

955f331a77 Fold (and (setcc X, C1), (setcc X, C2))
This is important for several reasons:

1. Benchmarks have lots of code that looks like this (perlbmk in particular):

  %tmp.2.i = setne int %tmp.0.i, 128              ; <bool> [#uses=1]
  %tmp.6343 = seteq int %tmp.0.i, 1               ; <bool> [#uses=1]
  %tmp.63 = and bool %tmp.2.i, %tmp.6343          ; <bool> [#uses=1]

   we now fold away the setne, a clear improvement.

2. In the more important cases, such as (X >= 10) & (X < 20), we now produce
   smaller code: (X-10) < 10.

3. Perhaps the nicest effect of this patch is that it really helps out the
   code generators.  In particular, for a 'range test' like the above,
   instead of generating this on X86 (the difference on PPC is even more
   pronounced):

        cmp %EAX, 50
        setge %CL
        cmp %EAX, 100
        setl %AL
        and %CL, %AL
        cmp %CL, 0

   we now generate this:

        add %EAX, -50
        cmp %EAX, 50

   Furthermore, this causes setcc's to be folded into branches more often.

These combinations trigger dozens of times in the spec benchmarks, particularly
in 176.gcc, 186.crafty, 253.perlbmk, 254.gap, & 099.go.

Implement (setcc (shl X, C1), C2) folding.

The second one occurs several dozen times in spec.  The first was added
just in case.  :)

These are tested by shift.ll:test2[12], and div.ll:test5

always guaranteed to exist. This fixes PR444. Thanks to Alkis
for reporting the bug and testing the patch.
AddRecord used to return a big list, but that return value was never
used. So now it doesn't return anything.

added notes on the fact that the current implementation uses
sbyte* for va_list.  Updated all occurances of valist to va_list (it was
inconsistant and find/replace is so easy ;-) ).  Added <...> around all
occurances of va_list in the intrinsic functions to match the vaarg and
vanext instructions and to further show that va_list is a variable type.
