Semi-pruned SSA support for sea-ir.
Added the following:
Per file:
sea_ir/sea.*: IDominator pass, dominance frontiers, global variables for ssa
transformation, phi-function insertion pass, SSA renaming pass.
sea_ir/instruction_tools.*: These tools provide info needed by dataflow analysis
that is dependent on dex format.
compiler/utils/scoped_hashtable.h: Scoped hashtable implementation that
allows fast SSA renaming.
src/compiler/utils/scoped_hashtable_test.cc: Test for scoped_hashtable.h.
dex_instruction.cc: Changed semantics of the VRegA,B,C function
to return NO_REGISTER instead
of aborting if the instruction does not
have register operands.
Android.common.mk: Added support for scoped_hashtable test.
