843c6c2d0e R600: Use a refined heuristic to choose when switching clause
This is using a hint from AMD APP OpenCL Programming Guide with
empirically tweaked parameters.
I used Unigine Heaven 3.0 to determine best parameters on my system
(i7 2600/Radeon 6950/Kernel 3.9.4) the benchmark :
it went from 38.8 average fps to 39.6, which is ~3% gain.
(Lightmark 2008.2 gain is much more marginal: from 537 to 539)

There is no lit test provided as the parameter were determined
empirically and it it would be nearly impossiblet to find a test
program that check for optimal behavior.

40be73bed7 Disallow i64 div/rem in PPC32 counter loops
On PPC32, [su]div,rem on i64 types are transformed into runtime library
function calls. As a result, they are not allowed in counter-based loops (the
counter-loops verification pass caught this error; this change fixes PR16169).

8fc760cbe8 ARM FastISel integer sext/zext improvements
My recent ARM FastISel patch exposed this bug:
  http://llvm.org/bugs/show_bug.cgi?id=16178
The root cause is that it can't select integer sext/zext pre-ARMv6 and
asserts out.

The current integer sext/zext code doesn't handle other cases gracefully
either, so this patch makes it handle all sext and zext from i1/i8/i16
to i8/i16/i32, with and without ARMv6, both in Thumb and ARM mode. This
should fix the bug as well as make FastISel faster because it bails to
SelectionDAG less often. See fastisel-ext.patch for this.

fastisel-ext-tests.patch changes current tests to always use reg-imm AND
for 8-bit zext instead of UXTB. This simplifies code since it is
supported on ARMv4t and later, and at least on A15 both should perform
exactly the same (both have exec 1 uop 1, type I).

2013-05-31-char-shift-crash.ll is a bitcode version of the above bug
16178 repro.

fast-isel-ext.ll tests all sext/zext combinations that ARM FastISel
should now handle.

Note that my ARM FastISel enabling patch was reverted due to a separate
failure when dealing with MCJIT, I'll fix this second failure and then
turn FastISel on again for non-iOS ARM targets.

I've tested "make check-all" on my x86 box, and "lnt test-suite" on A15
hardware.
