ager@google.com bf7163f1a6 Reapply: Use GVN for length loads from arrays and strings. 
- Fix bug in variable allocation.
- Treat all HCheck instructions the same when it comes to GVN. They do not have side-effects.

Changes since last version:

- give HTypeConversion a typeCode and implement typeEquals and dataEquals.
- clear side effects for array and string loads when enabling GVN.

ager@google.com 788f5af41a Reapply change to GVN all HFieldGet instructions. 
- Enable GVN for all HFieldGet.
- Mark all non-final HFieldGet as depending on something.
- Mark control flow as not having side effects.
- Fix dead code elimination to not treat control flow as dead code.
- Fix live ranges for HChecks to unconditionally have the same live range as the instruction they are checking.
- Added Nicolas' fix for GVN in loops (https://chromiumcodereview.appspot.com/10565025).

ngeoffray@google.com ec794c987c Remove the 'element' field on a HParameterValue to use the 'sourceElement' of HInstruction. Also, we should keep a type guard when we want a type that is a supertype of the declared type (eg we want num, the declared type is int).
