Removed an unneeded check for phis: There are never HValues in the work list
which are not convertible to integer and are not a phi. (But even if they were,
ignoring IsConvertibleToInteger() then looks like the wrong thing to do.)

Refactor Context::Lookup so it is more obvious.  Change the comment in
contexts.h so it no longer indicates that it can return an arguments
object (it can't) and clean up the call sites that had leftover dead code.

"SmartPointer should have been named SmartArrayPointer as it expects an input
allocated using new[] and deallocates it using delete[]. Using it as a simple

When we propagate the information that a value is not convertible to integer,
there is no need for a separate fixed-point computation, we can do things the
"Millikin way" (tm), folding as much computation as possible into a single pass:
;-) We already have the phi node reachability information, so we can easily
propagate this while doing the representation histogram computation.

SmartPointer expects an input allocated using new[] and deallocates it using delete[].
So using SmartPointer for deleting T* here is incorrect. Fix it now.

All the constructs that used it are now properly bracketed in the AST and we
handle abrupt exits without try/finally.  We can treat normal context exit
as occurring implicitly at the end of a body.

The use-def relation between phis is mainly "forwards" (i.e. from phis with
smaller IDs to ones with larger IDs), so the fixed point computation terminates
faster when iterate through the phis in a "backwards" manner. This is quite
visible in complex Mandreel-generated code, where a few hundred phis with
non-trivial use-def chains are generated.
