4f6979967d Mach-o MH_EXECUTE rewrite; work-in-progress 
On amd64, otool and lldb accept the results.
The entry point points to the unfilter and uncompress routines.
Somehow _start has been lost.

9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.
