3403b87cb7 More Control Flow Integrity (Intel) 
More ENDBRxx for CALL *%RDX for 'getbit'.
amd64: LEA xxx(%rip),%reg and STRCON section,
    instead of CALL; .asciz "..."; POP %reg
(Not for PE due to WINDOWS_BACK binary compatibility.)
i386 string constants still use call-.asciz-pop because no (%rip)

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.

ea2a190bd1 ELF2 main programs pass src/testsuite and upx-testsuite-v2 
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.

c924c32d54 ELF2: fix lzma on amd64-linux.elf-* 
New -DWINDOWS_BACK so that amd64-win64.pe.h does not change.
This hides a real bug (unchecked), but would change anti-virus status.

0515be4334 LZMA on AMD64 had bug in calling sequence, leading to random exit(127) 
LzmaDecode randomly decided that the input had ended in the middle,
because of error in interface between ELFMAINX and the decoder.

Thanks to Kevin Gosse!
