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.

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.

Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)

to support a different (de-)compression algorithm for each PT_LOAD.

Decompression escape hatch for ELF can require a new page.
...
If not enough room on last page of .text, and ElfXX_Ehdr not PF_X,
then the escape hatch must use a new page.

Needed: expert on TOC for big-endian. glibc, musl, gcc disagree
on layout (is the .func first?) and usage for .e_entry.
