Moved globals offsets calculation to the wasm module decoder, since
this is a property of the module, not of each instance.
Qualified as "const" references to WasmModule outside of the decoder

Since we can't OSR from an function compiled with Ignition, this makes it
impossible to tier up asm.js code as it is running. As such, this CL
bypasses Ignition for asm.js code.

Sequences like:
1: Load[kRepWord32|kTypeInt32](<address>, ...)
2: Word32And(1, <constant>)
3: Word32Equal(2, <another constant>)
4: Store[(kRepWord32 : NoWriteBarrier)](<address>, <value>)
5: Branch[None](3, ...) -> B1, B2
where #1 and #4 refer to the same memory location, are problematic because in VisitBranch we assume that 'InstructionSelector::CanCover()' is transitive.
What happens is that CanCover(5, 3) is true (3 is a pure op), and so are CanCover(3, 2), CanCover(2, 1), but the effect level of 5 and 3 never gets checked because 3 is a pure op. Upon VisitBranch, we ended up materializing:
mov [address], <value>
test [address], <another constant>
With this patch, it becomes:
mov reg, [address]
mov [address], <value>
test reg, <another constant>

This fixes the SharedFunctionInfo::num_literals field for global builtin
functions (e.g. {Object} and friends) to be accurate. The field was not
being updated by Runtime_SetCode. It also removes the dangerous and by
now obsolete JSFunction::NumberOfLiterals accessor.

There are bots on the chromium.lkgr waterfall that need to
be able to set v8_target_arch to "arm" while the rest of
the target build is "x86". This CL makes that argument
a declare_arg(), so that we can do that.

Script position calculation logic (i.e. line & column numbers for a
given code position) is now based on a single method
Script::GetPositionInfo(). Refactored related code in isolate.cc and
js/messages.js to use the new method. The line_ends accessor is still
in use by chromium and thus cannot be removed yet.

Previously, certain calls to DebugPushPromise and DebugPopPromise
happened always, without any check to see if we were in a debugging
environment. This patch adds a conditional check before making these
debug calls to make sure they aren't called when not needed.
Before the patch, running --prof over the bluebird benchmarks,
brings up these unprotected debug calls --
ticks cpp total name
16 6.7% 2.0% v8::internal::Runtime_DebugPushPromise(int, v8::internal::Object**, v8::internal::Isolate*)
7 2.9% 0.9% v8::internal::Runtime_DebugPopPromise(int, v8::internal::Object**, v8::internal::Isolate*)
This patch removes the above calls and provides a 4% improvement (with
a 2% variance over 10 runs) in the bluebird benchmark.

Previously, split-edge blocks inserted into CodeStubAssembler schedules
inherited the "deferredness" of their predecessor block. This tended to inline
newly inserted blocks that preceeded deferred code inline with non-deferred
code. The stack frame elider sometimes inserted stack construction into these
blocks, code which was actually was only needed in the deferred case.
This CL marks inserted split edge blocks with the deferredness of their
successors, e.g. they are defererred if their predecessor is deferrred. This
moves stack building code that logically belongs to deferred code into the
deferred code area rather than inlining it in non-deferred code.

This flag has been on by default for a while, along with
FLAG_track_prototype_users which provides the prerequisite
infrastructure. We are now sure that this is the direction
we want to go in, so in order to simplify the code, this CL
drops the respective flag-off code paths.
