6549163a55 Add roundsd instruction to ia32 and use it in optimized Math.floor. 
It is available platforms that have SSE 4.1 and allows us to handle
negative numbers without deoptimization. Before we would deoptimize
on negative inputs to Math.floor. x64 already uses this instruction.

* Change Math.floor unit test to make sure every test case gets
optimized by changing the source code for each test case.

* Fix HIR debug printing for some instructions.

These files already include v8.h so they don't need to define the
namespace alias again.

808748b44d Do not use deprecated ARM instructions in DirectCEntryStub::GenerateCall. 
Non-ancient versions of the ARM-ARM explicitly deprecate most uses of the PC
within instructions and older ARM implementations have a non-predictable offset
(8 or 12) for some of these deprecated uses. Avoiding the deprecated instruction
costs us one additional instruction in DirectCEntryStub::GenerateCall, but this
should not cause any significant performance degradation.

The deoptimizer still uses the PC in a stm instruction, but it is a bit unclear
what to do about that, so simply a comment has been added to reconsider this in
the future.

06bea35f7f Simplify and optimize ToBoolean handling. 
Changing our builtin JavaScript code slightly, we can make sure that we never
see internal objects as arguments for ToBoolean at runtime. Removing that case
from the stub generator and crankshaft makes things a lot easier.

Heap numbers can never be undetectable (only strings and spec objects can), so
we can leave out a useless test.

Try to re-use a non-null register value when returning 'true' in some cases.

Removed special handling of the 'handle all' case, it will very probably never
happen in real code and only makes things more complicated.

Improved naming of the ToBoolean stubs a bit, reflecting the order in which
cases are handled in the code itself.

* Bug fix for range analysis (contributed by Andy Wingo). Ranges of
double values have to include negative zero. Original code review:
 http://codereview.chromium.org/7514040/

* Fix a bug in optimized Math.round on ARM. When emitting minus-zero checks
we previously return a wrong result because of incorrect register assignment.

* Fix performance problem in IA32 and x64. Refine the checks
for minus zero and avoid unnecessary deoptimizations on Math.floor.

* Improve mjsunit test for Math.round to make sure we also
 get the optimized version of the code for each test case.
