6b4bd6b35c Move the #include of sys/stat.h inside the linux "hack" for the stat 
family of functions so it gets noticed if we ever remove this.

41925f87d3 Actually overload the virtual method. This fixes 
Regression/Analysis/GlobalsModRef/purecse.ll.  Isn't this what the
-Woverload-whatever flag would warn about :)

save small amounts of time for functions that don't call llvm.returnaddress
or llvm.frameaddress (which is almost all functions).

07f9f4e2a4 Fix a file overwrite bug in llvm-ar introduced by changes to 
createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.

c0354c904b Set the rounding mode for the X86 FPU to 64-bits instead of 80-bits. We 
don't support long double anyway, and this gives us FP results closer to
other targets.

This also speeds up 179.art from 41.4s to 18.32s, by eliminating a problem
with extra precision that causes an FP == comparison to fail (leading to
extra loop iterations).

077f1a8292 Though the previous xform applies to literally dozens (hundreds?) of variables 
in SPEC, the subsequent optimziations that we are after don't play with
with FP values, so disable this xform for them.  Really we just don't want
stuff like:

double G;   (always 0 or 412312.312)
  = G;

turning into:

bool G_b;
  = G_b ? 412312.312 : 0;

We'd rather just do the load.

dade2d22ba Two bug fixes: 
1. Actually increment the Statistic for the GV elim optzn
 2. When resolving undef branches, only resolve branches in executable blocks,
    avoiding marking a bunch of completely dead blocks live.  This has a big
    impact on the quality of the generated code.

With this patch, we positively rip up vortex, compiling Ut_MoveBytes to a
single memcpy call. In vortex we get this:

     12 ipsccp           - Number of globals found to be constant
    986 ipsccp           - Number of arguments constant propagated
   1378 ipsccp           - Number of basic blocks unreachable
   8919 ipsccp           - Number of instructions removed

59acc7d4ef This is the initial implementation of IPSCCP, as requested by Brian. 
This implements SCCP/ipsccp-basic.ll, rips apart Olden/mst (as described in
PR415), and does other nice things.

There is still more to come with this, but it's a start.

c4d6916508 Eliminate this ugly hack. This was put back in when replaceAllUsesOf used 
a different algorithm that was extremely inefficient for instructions with
many operands.

This reduces the time of this code snippet from .23s for 176.gcc to 0.03s
in a debug build, which speeds up total llvm-dis time just barely.

It's more of a code cleanup than a speedup.

ea1c45405d Do extremely simple sinking of instructions when they are only used in a 
successor block.  This turns cases like this:

x = a op b
if (c) {
  use x
}

into:

if (c) {
  x = a op b
  use x
}

This triggers 3965 times in spec, and is tested by
Regression/Transforms/InstCombine/sink_instruction.ll

This appears to expose a bug in the X86 backend for 177.mesa, which I'm
looking in to.
