Having beefed up GetKeys() to support everything, use it for everything now.
This fixes Object.getOwnPropertyNames and Object.getOwnPropertySymbols for
Proxies, and gets rid of a bunch of code duplication.

Create a visitor for evacuating objects for young and old generation. This is

Fix the missed store buffer entries for live objects on aborted pages. Marking
the page as scan_on_scavenge takes care of rebuilding the entries. Note that
this requires an additional case in the rebuilding logic as we cannot iterate an
aborted pages using the object layout, but rather have to use mark bits for
this.

For now, we revoke a proxy by setting its handler to null (as in the spec).
Change the "target" field from Object to JSReceiver as there's no point in
allowing more.

The expression Number(x) is essentially equivalent to ToNumber(x),
so just lower to JSToNumber in the JSCallReducer and let typing
and typed lowering take care of optimizations.

original commit message:
The Float32RoundTiesEven operator rounds float32 numbers towards the nearest
integer. If the distance to two integers is the same, then the result is
the even integer. This is the default rounding mode of the ieee 754 floating
point standard.
I implemented the optional Float32RoundTiesEven operator on x64, ia32, arm, and arm64.

The optimized code generated by Crankshaft cannot properly deal
with proxies (in the prototype chain), and there's probably no
point in trying to make that work^Wfast with Crankshaft at all.
TurboFan will handle that properly; Crankshaft just bails out
to fullcodegen, which then goes to the runtime, which should do
the right thing soon.

Fix several operations in the parser that rewrite constant expressions
to preserve knowledge regarding whether a value originally contained a ".".
This information is required to accurately validate Asm.js typing.
Making the assumption that if either side of a binary operation contains
a dot, that the rewritten expression should be treated as a double for
Asm.js purposes. This is a slight deviation from the spec (which
would forbid mix type operations).

I added a flag to the CallDescriptor which indicates that the native
stack should be used for a CallObject instead of the js stack on arm64.
Additionally I removed the use of EmitPrepareArguments because the
current implementation does not work when float and int parameters are
mixed. I plan to fix it in a future CL, because currently I have a
problem figuring out the type of a parameter.
