[turbofan] Implement the correct semantics for integer division/modulus.
Also fix the sdiv/udiv instructions on ARM as a nice side effect.

Remove v8stdint.h, it doesn't serve a purpose anymore.
Basically a follow-up to https://codereview.chromium.org/667573005/.

[arm] Drop SMMLS support.
Apparently
SMMLS r, b, c, a
computes
r = ((a << 32) - b * c) >> 32
while the documentation is kinda misleading and states that it should
compute
r = a - ((b * c) >> 32)
The actual behavior is kinda useless, so we drop the instruction again.

[turbofan] Fix HashCode/Equals for floating point operators.
Those floating point constant operators require bitwise handling of
their parameters, otherwise 0.0 equals -0.0. This is solved in a
general way by adding new base::bit_equal_to and base::bit_hash
function objects.

Further improve hashing of pointers and integers.
Also make sure that the appropriate functions are inlined properly
(using V8_INLINE instead of inline to enforce it even with GCC),
and improve the HashIsOkish unittest.

Move unit tests to test/unittests.
As per discussion on the V8 team, this is the place we want them to live,
not following the Chrome Style Guide for this.
