Adds option to build a V8 library statically, but with the options on
windows that allows it to be subsequently included in another DLL. On
Windows this is required for it to correclty link against the correct

Calling Runtime::kAbort through a builtin instead of the c-entry stub
will allow to generate the call in a background thread, because a
builtin provides its own handle, whereas a code stub does not.

This allows to pass deoptimization reasons to the profiler without the
requirement of always providing a source position. The absence of deopt
reasons is now communicated via a sentinel as the deopt id value. The

Introduce a proper CodeStubAssembler::BranchIfToBooleanIsTrue helper
method, that branches to if_true/if_false labels depending on whether
the value that is passed would yield true or false when fed to
ToBoolean. Use this helper to implement the bytecode handlers w/o having
to materialize the temporary booleans and essentially branching twice.
The CodeStubAssembler::BranchIfToBooleanIsTrue helper favors the most
likely case of a Boolean constant now.

Also migrate the ToBooleanStub to a ToBoolean TurboFan builtin, that
also uses the helper method under the hood.

Remove the now obsolete Oddball::to_boolean field.

The bug occurs because we do not canonicalize character class ranges
before adding case equivalents. While adding case equivalents, we abort
early for one-byte subject strings, assuming that the ranges are sorted.
Which they are not.

In int32 multiplication, if we have a positive integer as input, then we know we can't produce a -0 answer. The same is true if truncation is applied (x * y | 0). Without this information, we have to rather annoyingly check if the result of multiplication is 0, then OR the inputs to check for negativity, and possibly return -0. In TurboFan, we'll deopt in this case.
