If the input range is positive and the shift count is constant
we can replace >>> with >> to compute the output range.

For negative inputs, we can only compute a range if the 
result always fits into a signed int32.

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. ;-)

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.

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

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.

  support for darwin.

  This version of valgrind.h differs from the original in that all
  instances of "unsigned long long int" have been replaced with
  "uint64_t", as the former is not allowed in ISO C++ 89.
