The trace-events will have a high overhead when turned on, but they are in a disabled-by-default category. As long as the off overhead is negligible, this CL allows us to understand the behavior of V8 rather than its performance at the moment. The original CL was failing the TSAN builder, the variable in question was intended to be accessed quickly with no guarantee. Switched to using an Atomic variable with no barrier read/write.

The former will handle loads of predeclared global variables (vars and functions), lets, consts and undeclared variables. The latter will handle named loads from explicit receiver. In addition, named loads does not depend of the TypeofMode. TypeofMode related cleanup will be done in the follow-up CL.

Moves between operands with different representations shouldn't happen, so don't test them. This makes it easier to modify canonicalization to differentiate between floating point types, which is needed to support floating point register aliasing for ARM and MIPS. This change also expands tests to include explicit FP moves (both register and stack slot).

There's no need to have different versions of the fairly complex TransitionElementsKindStub just to avoid a single instance type check at execution time (which is used to figure out the effective length in case of JSArray objects).

This CheckBounds simplified operator is similar to the HBoundsCheck in Crankshaft, and is hooked up to the new type feedback support in the SimplifiedLowering. We use it to check the index bounds for keyed property accesses. Note to perf sheriffs: This will tank quite a few benchmarks, as the operator makes some redundant branch elimination ineffective for certain patterns of keyed accesses. This does require more serious redundancy elimination, which we will do in a separate CL. So ignore any regressions from this CL, we know there will be a few.

Port 7ceed92a Port 89d8c57b Original commit message: Import base::ieee754::atan() and base::ieee754::atan2() from fdlibm and introduce Float64Atan and Float64Atan2 TurboFan operators based on those, similar to what we already did for Float64Log and Float64Log1p. Rewrite Math.atan() and Math.atan2() as TurboFan builtin and use the operators to also inline Math.atan() and Math.atan2() into optimized TurboFan functions. Import base::ieee754::log1p() from fdlibm and introduce a Float64Log1p TurboFan operator based on that, similar to what we do for Float64Log. Rewrite Math.log1p() as TurboFan builtin and use that operator to also inline Math.log1p() into optimized TurboFan functions. Also unify the handling of the special IEEE 754 functions somewhat in the TurboFan backends. At some point we can hopefully express this completely in the InstructionSelector (once we have an idea what to do with the ST(0) return issue on IA-32/X87). Drive-by-fix: Add some more test coverage for the log function.
