Dynamic BCE (based on induction range analysis)

Rationale: A rewritten dynamic BCE that uses induction variable analysis
           to generate the run-time tests before a loop in order to
           eliminate bounds-checks from its body. This CL removes now
           obsoleted induction related code inside the BCE module.
           Also, the dynamic test generation is placed more strategically,
           since we missed a few cases where static analysis does better.

Most significant performance improvements (after filtering noise) is about:
  Linpack +20%

Fix ClinitCheck pruning.

Make sure we merge the ClinitCheck only with LoadClass and
HInvokeStaticOrDirect that is a part of the very same dex
instruction. This fixes incorrect stack traces from class
initializers (wrong dex pcs).

Rewrite the pruning to do all the ClinitCheck merging when
we see the ClinitCheck, instead of merging ClinitCheck into
LoadClass and then LoadClass into HInvokeStaticOrDirect.
When we later see an HInvokeStaticOrDirect with an explicit
check (i.e. not merged), we know that some other instruction
is doing the check and the invoke doesn't need to, so we
mark it as not requiring the check at all. (Previously it
would have been marked as having an implicit check.)

Remove the restriction on merging with inlined invoke static
as this is not necessary anymore. This was a workaround for
    X.test():
       invoke-static C.foo() [1]
    C.foo():
       invoke-static C.bar() [2]
After inlining and GVN we have
    X.test():
       LoadClass C (from [1])
       ClinitCheck C (from [1], to be merged to LoadClass)
       InvokeStaticOrDirect C.bar() (from [2])
and the LoadClass must not be merged into the invoke as this
would cause the resolution trampoline to see an inlined
frame from the not-yet-loaded class C during the stack walk
and try to load the class. However, we're not allowed to
load new classes at that point, so an attempt to do so leads
to an assertion failure. With this CL, LoadClass is not
merged when it comes from a different instruction, so we can
guarantee that all inlined frames seen by the stack walk in
the resolution trampoline belong to already loaded classes.

Add immune spaces abstraction

ImmuneSpaces is a set of spaces which are not reclaimable by the GC in
the current collection. This set of spaces does not have requirements
about space adjacency like the old ImmuneRegion. ImmuneSpaces generates
the largest immune region for the GC. Since there is no requirement on
adjacency, it is possible to have multiple non-adjacent applicaton
image files.

For image spaces, we also look at the oat code which is normally after
the application image. In this case, we add the code as part of the
immune region. This is required to have both the boot image and the
zygote space be in the same immune region (for performance reasons).

This reverts commit 55d02cf056f993aeafebd54e7b7c68c7a48507c9, and
makes the following change:
Currently we leverage loop side effects to decide whether heap values are
killed by the loop. Stores need to be kept if heap values may be killed
by loops and the corresponding loads cannot be eliminated. Similar thing
need to be done for each predecessor when we merge predecessor heap values.
To do that, the HInstanceFieldSet instruction itself is put in the heap
value array instead of the value of the store instruction. The store
instruction may be added to possibly_removed_stores_ first, but can later
be removed from possibly_removed_stores_ when it's found out that the store
needs to be kept due to merging/loop side effects.
