adding big-endian support across compiler, runtime, and library modules

Browse source 
- adding Platform.LittleEndian to centralize endianness detection
- using SYSTEM.GET with correct byte offset for HUGEINT to smaller type reads on big-endian
- fixing Reals.BytesToHex iteration direction and InitEndian for big-endian
- fixing oocLowReal fraction, IsInfinity, IsNaN using Reals.Expo/SetExpo
- fixing Math.ToREAL and MathL.exponent for big-endian
- fixing In.Int and In.LongInt for big-endian
- fixing outtest.wh byte iteration direction for big-endian
- regenerating all bootstrap C sources
- tested on ppc32
