Support hardware divide instruction
Bug: 11299025
Uses sdiv for division and a combo of sdiv, mul and sub for modulus.
Only does this on processors that are capable of the sdiv instruction, as determined
by the build system.
Also provides a command line arg --instruction-set-features= to allow cross compilation.
Makefile adds the --instruction-set-features= arg to build-time dex2oat runs and defaults
it to something obtained from the target architecture.
Provides a GetInstructionSetFeatures() function on CompilerDriver that can be
queried for various features. The only feature supported right now is hasDivideInstruction().
Also adds a few more instructions to the ARM disassembler
b/11535253 is an addition to this CL to be done later.
