Special case the recording of constant pool entries in the slot buffer.
This CL enables RelocInfo pointers which live in the constant pool to be treated
as normal pointers by the slot buffer, avoiding the requirement of creating fake
RelocInfo objects during UpdateSlots() in order to update these slots. This
is possible because constant pool entries are just pointers and don't require
the RelocInfo machinary to be updated.
EmbeddedObject constant pool entries can be added untyped to the slot buffer,
while code targets are still typed in order to correctly update the target
address based on the relocated code object.
Note: this is required in order to enable OOL constant pool support on Arm, but
should be benifitial for the current inline constant pool used by Arm code.

Refactor script compilation / running & use of helper funcs in test-api.cc.
The tests were using different kind of constructs for achieving the same
thing. This makes refactoring the compilation API more difficult than it should
be.
cctest.h already contained helpers for compiling and running scripts, but they
were not used consistently.
For example, all these were used for running scripts:
v8::Script::Compile(v8_str("foo"))->Run();
v8::Script::Compile(v8::String::NewFromUtf8(isolate, "foo))->Run();
CompileRun(v8_str("foo"));
CompileRun(v8::String::NewFromUtf8(some_way_to_get_isolate(), "foo"));
v8::Local<v8::Script> script = any_of_the_above; script->Run();
Most of the tests just want to run a script (which is in const char*) and don't
care about how the v8::String is constructed or passed to the compiler API. Using
the helpers makes the test more readable and reduces boilerplate code which is
unrelated to what the test is testing.

MIPS: Consistenly handle power-of-2 divisors in division-like operations.
Port r19715 (0d6d244)
Original commit message:
Lithium currently supports 3 division-like operations on integral
operands: "Normal" division (rounding towards zero), flooring division
(rounding towards -Infinity) and modulus calculation (the counterpart
for the "normal" division). For divisors which are a power of 2, one can
efficiently use some bit fiddling to avoid the actual division for such
operations. This CL cleanly splits off these operations into separate
Lithium instructions, making the code much more maintainable and more
consistent across platforms.
There are 2 basic variations of these bit fiddling algorithms: One
involving branches and a seemingly more clever one without branches.
Choosing between the two is not as easy as it seems: Benchmarks (and
probably real-world) programs seem to favor positive dividends,
registers and shifting units are sometimes scarce resources, and branch
prediction is quite good in modern processors. Therefore only the
"normal" division by a power of 2 is implemented in a branch-free
manner, this seems to be the best approach in practice. If this turns
out to be wrong, we can easily and locally change this.

Consistenly handle power-of-2 divisors in division-like operations
Lithium currently supports 3 division-like operations on integral operands: "Normal" division (rounding towards zero), flooring division (rounding towards -Infinity) and modulus calculation (the counterpart for the "normal" division). For divisors which are a power of 2, one can efficiently use some bit fiddling to avoid the actual division for such operations. This CL cleanly splits off these operations into separate Lithium instructions, making the code much more maintainable and more consistent across platforms.
There are 2 basic variations of these bit fiddling algorithms: One involving branches and a seemingly more clever one without branches. Choosing between the two is not as easy as it seems: Benchmarks (and probably real-world) programs seem to favor positive dividends, registers and shifting units are sometimes scarce resources, and branch prediction is quite good in modern processors. Therefore only the "normal" division by a power of 2 is implemented in a branch-free manner, this seems to be the best approach in practice. If this turns out to be wrong, we can easily and locally change this.
