Set Processes comm name to package name

When debugging audit logs, it is often helpful to
have the packages name. Bear in mind that the
package name is the right most chars up to
TASK_COMM_LEN. Although a possibility of truncation
exists, it can be useful for narrowing down the
possibilities.

Dalvik: Add sdiv support in the interpreter

This patch adds hardware divide support in the interpreter side of
dalvik. This operation is supported on new armv7 cpus such as A15 or A7.

Opcodes added:
    OP_DIV_INT
    OP_DIV_INT_2ADDR
    OP_DIV_INT_LIT16
    OP_DIV_INT_LIT8
    OP_REM_INT
    OP_REM_INT_2ADDR
    OP_REM_INT_LIT16
    OP_REM_INT_LIT8

Dalvik: Add sdiv support in the JIT

This patch adds hardware divide support in the JIT side of dalvik.
This operation is supported on new armv7 cpus such as A15 or A7.

The following opcodes are enabled and will generate code based using
SDIV instruction:

        OP_DIV_INT
        OP_DIV_INT_2ADDR
        OP_REM_INT
        OP_REM_INT_2ADDR
        OP_DIV_INT_LIT16
        OP_DIV_INT_LIT8
        OP_REM_INT_LIT16
        OP_REM_INT_LIT8

Dalvik: Add hardware support for OP_LONG_TO_DOUBLE in the interpreter

The following patch adds hardware vfp support for OP_LONG_TO_DOUBLE
in the interpreter. Previously this opcode was implemented using one of
gcc's builtin helpers.

Don't implicitly cast NULL to a bool

The code is wrong and causes an error when building with clang 3.4

Change exception message for ArrayStoreException.

The exception message is tested in SystemTest. I'm not sure
what's worse: Changing the dalvik message or changing the test
to be happy with both messages.

(I assume the art message is the one we chose because it's more
recent.)

Fix dx test 034.

- Test 034 requires that a dex file is dumped in a human readable form
even if the dex file does not contain ClassDef.
Consequently, the command line behavior is modified to satisfy this requirement.
