* chunk. The two dependent fields are bitmap and decommittedArenas.
*
* For the mark bitmap, we know that each arena will use a fixed number of full
* bytes: ArenaBitmapBytes. The full size of the header data is this number
* multiplied by the eventual number of arenas we have in the header. We,
* conceptually, distribute this header data among the individual arenas and do
* not include it in the header. This way we do not have to worry about its
* variable size: it gets attached to the variable number we are computing.
*
* For the decommitted arena bitmap, we only have 1 bit per arena, so this
* technique will not work. Instead, we observe that we do not have enough
* header info to fill 8 full arenas: it is currently 4 on 64bit, less on
* 32bit. Thus, with current numbers, we need 64 bytes for decommittedArenas.
* This will not become 63 bytes unless we double the data required in the
* header. Therefore, we just compute the number of bytes required to track
* every possible arena and do not worry about slop bits, since there are too
* few to usefully allocate.
*
* To actually compute the number of arenas we can allocate in a chunk, we
* divide the amount of available space less the header info (not including
* the mark bitmap which is distributed into the arena size) by the size of
* the arena (with the mark bitmap bytes it uses).

* of the API to serialize JS runtime state (script bytecodes, atom maps,
* object graphs, etc.) for later restoration. These portions
* are implemented in various appropriate files, such as jsscript.c
* for the script portions and jsobj.c for object state.
* - the callback APIs through which the runtime requests an opaque
* representation of a native object, and through which the runtime
* constructs a live native object from an opaque representation. These
* portions are the responsibility of the native object implementor.
* - utility functions for en/decoding of primitive types, such as
* JSStrings. This portion is implemented in jsxdrapi.c.

* Step 4: Now define the CheckedInt class.
*/
/**
* @class CheckedInt
* @brief Integer wrapper class checking for integer overflow and other errors
* @param T the integer type to wrap. Can be any type among the following:
* - any basic integer type such as |int|
* - any stdint type such as |int8_t|
*
* This class implements guarded integer arithmetic. Do a computation, check
* that isValid() returns true, you then have a guarantee that no problem, such
* as integer overflow, happened during this computation, and you can call
* value() to get the plain integer value.
*
* The arithmetic operators in this class are guaranteed not to raise a signal
* (e.g. in case of a division by zero).
*
* For example, suppose that you want to implement a function that computes
* (x+y)/z, that doesn't crash if z==0, and that reports on error (divide by
* zero or integer overflow). You could code it as follows:
@code
bool computeXPlusYOverZ(int x, int y, int z, int *result)
{
CheckedInt<int> checkedResult = (CheckedInt<int>(x) + y) / z;
if (checkedResult.isValid()) {
*result = checkedResult.value();
return true;
} else {
return false;
}
}
@endcode
*
* Implicit conversion from plain integers to checked integers is allowed. The
* plain integer is checked to be in range before being casted to the
* destination type. This means that the following lines all compile, and the
* resulting CheckedInts are correctly detected as valid or invalid:
* @code
// 1 is of type int, is found to be in range for uint8_t, x is valid
CheckedInt<uint8_t> x(1);
// -1 is of type int, is found not to be in range for uint8_t, x is invalid
CheckedInt<uint8_t> x(-1);
// -1 is of type int, is found to be in range for int8_t, x is valid
CheckedInt<int8_t> x(-1);
// 1000 is of type int16_t, is found not to be in range for int8_t,
// x is invalid
CheckedInt<int8_t> x(int16_t(1000));
// 3123456789 is of type uint32_t, is found not to be in range for int32_t,
// x is invalid
CheckedInt<int32_t> x(uint32_t(3123456789));
* @endcode
* Implicit conversion from
* checked integers to plain integers is not allowed. As shown in the
* above example, to get the value of a checked integer as a normal integer,
* call value().
*
* Arithmetic operations between checked and plain integers is allowed; the
* result type is the type of the checked integer.
*
* Checked integers of different types cannot be used in the same arithmetic
* expression.
*
* There are convenience typedefs for all stdint types, of the following form
* (these are just 2 examples):
@code
typedef CheckedInt<int32_t> CheckedInt32;
typedef CheckedInt<uint16_t> CheckedUint16;
