fschneider@google.com cfab482b84 Follow-up fix to my change to IsPowerOfTwo: Alignment of one means no alignment, not zero. 
We assert that the alignment is a power of two. Therefore, platforms that do not need 
alignment should return alignment of one instead of zero.

asiva@google.com b4d9e0d620 Auto create ApiLocalScope before calling native functions, this ensures that 
native functions do not have to call Dart_EnterScope/Dart_ExitScope
when they callback into the VM.

Remove Dart_EnterScope/Dart_ExitScope calls around native functions in 'bin'

zra@google.com dad3270d95 Implements far branch targets for MIPS. 
This change adds a flag --mips-far-branches, which when set causes
relative branches to be converted to absolute branches by determining
the PC, adding the branch offset to it, and using the jr or jalr
instruction to jump if the branch test passes.

This procedure clobbers the assembler temporary TMP, so TMP can no
longer be used in a branch test or in the branch delay slot of a
relative branch. Because TMP can't be used in a branch test, a
new temporary is introduced CMPRES2. This change replaces TMP with
CMPRES1 or another register where TMP can no longer be used.

Tests that were failing due to a too-far relative have the
--mips-far-branches flag set.

zra@google.com f6da1febeb Drops into Simulator Debugger only in a session that is already interactive. 
This change backs out an earlier change to the disassemblers that
made them return false if an instruction couldn't be decoded.
This was used in the simulator debuggers for arm and mips to avoid
executing an instruction that couldn't be decoded.

Instead, now when an unknown instruction is encountered in the simulator,
if the simulator is running interactively, we drop into
the debugger, and otherwise die. We detect that a simulator is
running interactively by setting a flag if we enter the debugger
for a user set break point.
