This change will ensure that all non-optimized code will be compiled
with debug break slots when debugging is initiated. This is handled by
scanning the heap for non-optimized functions without debug break slots and setting their code to be lazy recomplied. When the lazy recompilation happens the code will ge generated with debug break slots (if debugging is still active at that point in time).

Currently this is only implemented for functions which do not have activations on the stack.

Use the BitField helper class for the code flags, so that we do not have to
define both a shift and a mask explicitly.  This makes changing the flags
layout simpler.

Also, make the 'mask' and 'max' members of BitField into constants, because
they are constant and so that they can be used as constant expressions.
E.g., so they can be used in declaring other const members or in static
asserts.

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

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.
