ART: Boolean simplifier fix
Boolean simplifier should not remove condition instruction
if it has side effects.

ART: Simplify Ifs with BooleanNot condition
If statements with negated condition can be simplified by removing the
negation and swapping the true and false branches.

ART: Simplify more bool operations
Now that we have the HBooleanNot instruction, the instruction
simplifier can optimize out more conditions comparing a boolean
against a constant, as well as sequences of Boolean negations.

ART: Boolean simplifier
The optimization recognizes the negation pattern generated by 'javac'
and replaces it with a single condition. To this end, boolean values
are now consistently assumed to be represented by an integer.
This is a first optimization which deletes blocks from the HGraph and
does so by replacing the corresponding entries with null. Hence,
existing code can continue indexing the list of blocks with the block
ID, but must check for null when iterating over the list.
