Log message:
* Runs test1_dietlibc on x86!
* Added configure test for endianness, and change byteswaps to no-op if
* No longer mmap() program segments where they expect to go in memory, since
that's where ciel is loaded on x86.  Now we just malloc() the area and set
a global address offset.
* Abstract all x86-space memory access through new class x86_ptr, which takes
care of byteswapping and adding the above offset to addresses.
* Instruction pointer now includes a "context" field, so that we can actually
tell the difference between a real instruction pointer and a virtual one
which is an index into an array of decoded instructions.
