e48ec1c4bd Use type info for the ToBoolean translation in crankshaft. 
To do this, the Branch instruction needs to carry around a temporary register,
but only when the crankshafted code will make a map access. When the
crankshafted code sees an object of a type it hasn't encountered before, it will
always trigger a deopt. Another option in theses cases would be calling a
ToBooleanStub which can handle all types, but then one has to be careful to
*not* trigger a GC (which is currently a bit tricky to achieve).

Const-corrected ToBoolean::Types. Moved the NeedsMap logic into ToBoolean::Types
itself, where it belongs.

This patch improves a lot of benchmarks, crypto-orig even by 16.7%, but slows
down others. The slowdown has to be investigated, but I'd like to get this patch
out first to fix the flakiness problems we currently have due to the previous
crankshafted ToBoolean.

73f8cec70e Do not explicitly record undetectable objects in the ToBoolean stub. 
Loading the map within the stub already implies a check for an undetectable
object, so there is no need to record this separately. Furthermore, this brings
the size of the type info to record down to 8 bits, removing the need to find a
place for the ninth bit in the Code object. ;-)

f7138b1427 Implement a type recording ToBoolean IC. 
The IC records the set of types it has seen, e.g. {String} or {Boolean,
Undefined}, etc.  Note that in theory this could lead to a large number of
different ToBoolean ICs (512, to be exact, because we distinguish 9 types),
but in practice only a small handful of them are actually generated.

Currently the type recording part is only implemented on ia32, other platforms
continue to work like they did before, though.

Removed some dead code on the way.

7a0adba963 Fix overlap check in MoveBlock and fix assertion. 
The old code was adding a size in words to a byte*. Should use size in
bytes. Also, the assertions were doing signed comparisons on pointers
instead of unsigned. Fixing the assertions makes one of the assertions
identical to the condition just before it.

96e3482731 Implement mapping randomization for 64-bit Linux. Notes: 
- 32-bit Linux already seems to scatter the mmap() chunks around; 64-bit didn't.
- Seed the system random number generator a little better (we needlessly
trunctaed microsecond resolution to millisecond resolution).
- Will automatically take advantage of better entropy when V8::RandomPrivate
uses it.
