Fix issue with prototype of WeakMap constructor.
...
The WeakMap constructor didn't have a unique prototype, so it shared one with
Object. All WeakMap functions (including "get" and "set") were installed on
that prototype.

Do not use deprecated ARM instructions in DirectCEntryStub::GenerateCall.
...
Non-ancient versions of the ARM-ARM explicitly deprecate most uses of the PC
within instructions and older ARM implementations have a non-predictable offset
(8 or 12) for some of these deprecated uses. Avoiding the deprecated instruction
costs us one additional instruction in DirectCEntryStub::GenerateCall, but this
should not cause any significant performance degradation.
The deoptimizer still uses the PC in a stm instruction, but it is a bit unclear
what to do about that, so simply a comment has been added to reconsider this in
the future.

Simplify and optimize ToBoolean handling.
...
Changing our builtin JavaScript code slightly, we can make sure that we never
see internal objects as arguments for ToBoolean at runtime. Removing that case
from the stub generator and crankshaft makes things a lot easier.
Heap numbers can never be undetectable (only strings and spec objects can), so
we can leave out a useless test.
Try to re-use a non-null register value when returning 'true' in some cases.
Removed special handling of the 'handle all' case, it will very probably never
happen in real code and only makes things more complicated.
Improved naming of the ToBoolean stubs a bit, reflecting the order in which
cases are handled in the code itself.

Revert "Revert "Fix a bug in scope analysis.""
...
Reapply r8838 with a fix for the issue of function names.
Because function names can be added/changed/removed through the API,
remember whether the function is anonymous when initially parsed and use
that information when compiling.
