Use 64-bit integer counters for tracking time, rather than doubles.  This will be more atomic op friendly.

generated code was apparently doing stores directly into the return value
aggregate; now, it's doing a copy from a compiler-generated static object.
That object is initialized using [4 x i8] which breaks the test.  I believe
this change preserves the original point of the test.

Of course it would be better for the code to do stores directly into the
return aggregate, but that is not what happens at -O0; the llvm optimizers
seem to do that on x86 but not on ppc32, possibly because of the explicit
padding (which is unavoidable).  I think it must have been being done by
a gcc optimizer pass before.

cleans up the CMake-based build system a bit. Started by a patch from
Xerxes Rånby.

also some contribution from Jim Grosbach, Bob Wilson, and Evan Cheng.

I've done my best to consolidate the patches with those that were done by
Viktor Kutuzov and Anton Korzh from Access Softek, Inc. Let me know if missed
anything. I've completely reorganized the thumb2 td file, made more extensive
uses of multiclass, etc.

Test cases will be contributed later after I re-organize what's in svn first.

Fold the add (ptr, offset) into ptr[offset] only if the offset is small enough. movwi and moviw allow value of 5-bits only (i.e. 32).

Only pad when the section size > 0 and move the code that deals
with globals initializers to a place we know for sure the global
is initialized.

This is still a work in progress but most of the NEON instruction set
