John Reiser ed0665407a More: prefer movzbl over movb fetch to register 
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.

Decompressing lzma required many adjustments.
Backwards compatibility probably is broken for
    stub/amd64-win64.pe.h
    stub/arm64-win64.pe.h
Also: shared libraries need memfd_create.

John Reiser c36977f0b1 ELF: amd64-linux main programs use 2-step de-compressor 
The first $ARCH to move to 2-step de-compressor for ELF main programs.
De-compressor uses memfd_create to comply with strictest SELinux
settings (no PROT_WRITE on any PROT_EXEC page).
First step de-compressor always uses NRV2B to de-compress the second step,
and the second step can use a different de-compressor for each PT_LOAD.
