38b91a4ffe Fix issue 1076 by resetting labels of switch-clauses before use. 
If we compile a function literal twice with the full code generator,
we must make sure that the labels embedded in the AST are reset.

0e183035a2 ARM: Merging constants in simulator and assembler header files and other cleanup. 
First stab at a general ARM cleanup patch. It merges ARM constants so that they can be used across simulator, assembler and disassembler, and tidies up some syntax and ambiguities.

99a5b9f713 ARM: Initial type recording binary operation stub 
This implements the type recording binary operation stub for ARM. This first iteration only supports ADD. Handling of 32-bit integers is currently not implemented but just transitions. The generic case for now delegates to the generic binary operation stub.

Revert this change again.  Somewhat mysteriously we sometimes get empty
contexts that we do not expect in the context chain.

9c2d52eb0e 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.

8a9eeaf8da 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.

70910af7a0 Fix an assertion failure in the full code generator. 
We hit an assertion failure when we tried to record the AST ID of
the (shared) .arguments variable proxy more than once.  This was hit
when we had multiple calls to the same parameter in a function that
used the arguments object.  The fix is to not visit the subexpressions
of the (shared) property access expression.

ace6290452 Fix issue 974. 
When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception.  In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

830185b175 Clean up some messiness in Scopes. 
For some reason, the scope's arguments and arguments shadow were
variable proxies, which resulted in all references to the arguments
shadow being shared in the AST.  This makes it hard to put per-node
state on the AST nodes.

I took the opportunity to remove Variable::AsVariable which has
confused people in the past, and to rename Variable::slot to the more
accurate Variable::AsSlot.
