[ARM] Expand the use of integer division
https://bugs.webkit.org/show_bug.cgi?id=115138
Reviewed by Benjamin Poulain.
If availability of hardware integer division isn't known at compile
time, check the CPU flags and decide at runtime whether to fall back
to software. Currently, this OS-specific check is implemented on QNX.
Moreover, use operator % instead of fmod() in the calculation of the
software modulo. Even when it's software-emulated, operator % is faster
than fmod(): on ARM v7 QNX, without hardware division, we noticed
>3% speedup on SunSpider.

The iOS ABI is a little different than regular ARM ABI regarding stack alignment.
The requirement is 4 bytes:
"The ARM environment uses a stack that—at the point of function calls—is 4-byte aligned,

It should. This doesn't cause us to leak physical memory, but it does cause us to leak virtual
address space (and probably mach ports), which is also bad :-( FixedVMPoolExecutableAllocator
also has this bug, but it doesn't matter much because there's only one instance of that class
throughout the entire lifetime of the process, whereas each VM has its own SuperRegion.

DFG doesn't support to_jsnumber
https://bugs.webkit.org/show_bug.cgi?id=115129
Reviewed by Geoffrey Garen.
Based on Oliver's patch. Implements to_jsnumber as Identity(Number:@thingy), and then does
an optimization in Fixup to turn Identity(Number:) into Identity(Int32:) if the predictions
tell us to. Identity is later turned into Phantom.
Also fixed BackPropMask, which appeared to have NodeDoesNotExit included in it. That's
wrong; NodeDoesNotExit is not a backward propagation property.
Also fixed Identity to be marked as CanExit (i.e. not NodeDoesNotExit).
This more than doubles the FPS on ammo.

Reviewed by Filip Pizlo.
Fix NodeNeedsNegZero flag propagation in BackwardPropagationPhase.
Function arithNodeFlags should not mask NodeNeedsNegZero flag for ArithNegate and DoubleAsInt32
nodes and this flag should be always used to decide where we need to generate nezative-zero checks.
Remove unnecessary negative-zero checks from integer ArithDiv on ARM.
Also remove such checks from integer ArithMod on ARM and X86, and make them always to
check not only "modulo_result == 0" but also "dividend < 0".
Generate faster code for case when ArithMod operation divisor is constant power of 2 on ARMv7
in the same way as on ARMv7s, and add negative-zero checks into this code when needed.
Change speculationCheck ExitKind from Overflow to NegativeZero where applicable.
This shows 30% speedup of math-spectral-norm, and 5% speedup
on SunSpider overall on ARMv7 Linux.

Add watchdog timer polling for the DFG.
https://bugs.webkit.org/show_bug.cgi?id=115134.
Reviewed by Geoffrey Garen.
The strategy is to add a speculation check to the DFG generated code to
test if the watchdog timer has fired or not. If the watchdog timer has
fired, the generated code will do an OSR exit to the baseline JIT, and
let it handle servicing the watchdog timer.
If the watchdog is not enabled, this speculation check will not be
emitted.
