Avoids hardware failure of writing 0x00 instead of the fetched byte.
1 cycle faster, 1 byte larger (but often recouped later when OR of 32-bits).
Avoid changing win*pe.S for now.

Many changes for ELF shared libraries on Linux and Android

Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)
required extensive changes. But the bonus is the infrastructure
to support a different (de-)compression algorithm for each PT_LOAD.
