Break point at calls are currently set via IC. To change this, we
need to set debug break slots instead. We also need to distinguish
those debug break slots as calls to support step-in.
To implement this, we add a data field to debug break reloc info to
indicate non-call debug breaks or in case of call debug breaks, the
number of arguments. We can later use this to find the callee on the
evaluation stack in Debug::PrepareStep.

When running without a snapshot, the GlobalEval function gets lazy compiled.
By the time we compile it, its name is "eval", which causes the parser to
choke (functions named "eval" aren't allowed in strict mode!).
Instead, we now always skip checking the function name when lazy-parsing,
as the name has already been checked appropriately by the preparser.
Also cleaned up other cases that don't require name checking by introducing
FunctionNameValidity enum and passing appropriate values throughout the
parser and preparser.
This lets us pass an additional 18 test262 tests.

This basically means that we must not use the b(Label*) version here,

The b, bl and blx methods that take labels basically ignore the constant
pool check and just block the constant pool for the next instruction.
This way a long enough sequence of those instructions will block can
potentially block the constant pool emission for too long.

The invariant is that as long as there is a debug info on
the shared function info, no accessor IC is compiled for
its code. That way we can guarantee that stepping into
accessors, which requires a debug info, works for accessors.

This one occurred when serializing an object. When the property getter threw an
exception, that value was skipped, but the property count wasn't updated. The

If we compile handlers to call accessors, Debug::HandleStepIn won't get
called. Therefore we need to clear ICs each time. This has not been
necessary before because we used to patch ICs for breaking, and restored
them with cleared ICs. This is no longer the case. We do not use ICs
for breaking anymore, so they are not implicitly cleared any longer.
