8d47a6f625 Fixed an off-by-one error in SplitConstantsInFullCompiler test. 
The test tried to disassemble the last entry in a constant pool, which only
worked by accident until address randomization was introduced.

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.

5fba76891b Re-apply: Implement mapping randomization for 64-bit Linux. 
- 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.

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

d0ee5982a8 ICU 4.6 NumberFormat::EStyle enum is gone in ICU 4.8. Adding #if #else to make it work across versions. 
There was an ICU cleanup (removing all C++ style enums and replacing them with plain C enums). NumberFormat::EStyle had a draft status (from ICU 4.2) and it was cut. Confusion came up because DateFormat::EStyle is stable and won't be removed.

85f5afb717 Correctly mark functions from our natives files during compilation. 
When creating a CompilationInfo we always have the script and can
determine if it is a natives script.

Now that all natives functions are recognized as such, many of them
are called with undefined as the receiver. We have to use different
filtering for builtins functions when printing stack traces.

Also, fixed one call of CALL_NON_FUNCTION to be correctly marked as a
method call (with fixed receiver). Now that CALL_NON_FUNCTION is
marked as a native function this caused the receiver to be undefined.

55336b37bd Fixed confusion between AST IDs and condition codes on ARM. 
C++'s 'great' idea of implicitly converting an enum to an integral value hit us
again, this time resulting in silly (but currently non-harmful) entries in the
relocation table. Encapsulated the AST ID recording a bit, which helped a lot to
find the culprit.
