Revert "Reapply change to with/arguments interaction."
...
Revert this change again. Somewhat mysteriously we sometimes get empty
contexts that we do not expect in the context chain.

Fix a bug in delete for lookup slots.
...
The function Runtime_LookupContext searches the context chain for a
LOOKUP slot and returns the object holding the slot. It returned the
global context if the slot was not found or if it was found in a
function's context or arguments object. This is not the correct
object to use for 'delete'.
Since this lookup function is only ever used when deleting LOOKUP
slots (those that have to go through a with or a scope with eval), it
is simply replaced with a Runtime_DeleteContextSlot function that does
the appropriate thing for all kinds of context lookups.
This fixes Chromium bug 70066.

Reapply change to with/arguments interaction.
...
This is svn r6415 with a bugfix.
The bug was that we can have scopes with 0 heap slots (functions with
such scopes do not need a local context) and scopes with at least
Context::MIN_CONTEXT_SLOTS. The code generator only allocated a local
context if there were strictly more than Context::MIN_CONTEXT_SLOTS.
Before the change to with/arguments, it was impossible to actually get
a function scope with exactly Context::MIN_CONTEXT_SLOTS because every
such scope included a heap-allocated arguments (and arguments shadow)
slot.

ARM: Add instructions VFPCompareAndSetFlags and VFPCompareAndLoadFlags to macro assembler
...
Also removed the SBit from the vcmp instruction as it is not part of the instruction.
