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.

25e6a31004 i386 stub: prefer movzbl over movb fetch 
32-bit mode on x86_64 hardware can fail movb fetch to register
by writing 0x00 randomly instead of the fetched byte.
Note that most CPU can write only 32 or 64 bits to the register file,
so writing just 8 or 16 bits incurs a 1-cycle penalty in order to
form 32 bits by Read-Modify-Write of the destination register.
