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.

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).

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.

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.

Fix bugs and add a few small useful features:
* Fix Schedule view to properly parse schedule output and respond to switching
back to graph views.
* Add shorcuts for showing edges of selected nodes.
- 'i' shows all inputs
- 'o' shows all outputs
- '1'-'9' shows all nodes nth input where 1 <= n <= 9
- 'c' shows all control inputs
- 'e' shows all effect inputs
* Holding the control key down when using a edge-showing shortcut toggles edge
state rather the just showing.
* 'a' selects all nodes in graph view.
* Node selection is preserved between graph views and Schedule views.
* Holding control key down when using regular expression search shows currently
hidden nodes that match the regex search.
* Pane expansion buttons now respond to clicks in entire button area.
* Default text in regex search box makes searching more discoverable.

When running with FLAG_runtime_call_stats, native accessor accesses must
go through the runtime for accurate accounting. Previously the slow_stub()
was used as a handler in order to accomplish this, but it could never be
looked up from the code cache successfully due to mismatched code flags,
which could cause more handler recompilations than in normal operation.
This patch fixes that by emitting a runtime call into the compiled
handler instead of using the slow_stub().
Drive-by cleanup: drop the unused StoreIC_Megamorphic builtin.
