Do proper dispatch on declaration type instead of mingling together
different code generation paths. Once we add more declaration forms,
this is more scalable.

In separate steps, I'd like to (1) clean up the logic for DeclareGlobal,
and (2) try to reduce the special handling of the name function var if
possible.

The stats data have only count field at the moment.
A constantly growing array of integers also can be a reason of a leak.
Ans we have to have a way to detect such kind of leaks.

Drive by fix:
FindObject and AddEntry were replaced with FindEntry/FindOrAddEntry pair.

MinGW-w64 uses the rcx register for the first argument. Unlike MSVC, it does not require preparing a slot for the result handle on the stack and putting a pointer to it in the rcx register.

2.) When push-to-trunk was not called with "-c /path/to/chrome/src", explicitly ask for the path to help discoverability of the feature.
3.) Correctly convert "BUG=chromium:123" to "(Chromium issue 123)" in the pre-made ChangeLog entry.

Port r11282 (bd2ab07).

Patch by Daniel Kalmar.

Original commit message:

Some GWT compiled code results in array access that has a heap number (e.g. -0)
as an index. Until now this would result in a generic IC.

For example:

a[-0] === a[0] or

a[0.25 * 4] === a[1]

This change detects heap numbers that are representable as a smi
and converts them. As a result we can still use the fast keyed monomorphic
ICs. Optimized code already handles keyed access with a double-key efficiently.

As a result the frame rate on the reported benchmark improves by roughly 2x.

Although things are currently OK here, in the future it won't be enough to check
for the existence of a CALLBACKS result, we must additionally check that it
actually contains an accessor. In a nutshell: 'sed s/IsFound/IsProperty/' once
again...

Additionally, the control flow in DefinePropertyAccessor has been simplified by
using a helper function.

This fixes alignment issues on MIPS HW, found for example in mjsunit external-array.
