Fixes 16bit addr offset calculation
...
In the case of 16bit addressing mode, the upper bits 16bits are zext
prior to result.

Fixes more 16bit modrm addressing problems
...
In the case of an instruction that used 16bit addressing mode. It would
calculate the amount of displacement needing to be read using a 32bit
modrm mode. It would then read calculate modrm displacement again and
read the correct number of bytes.
Leftover bytes would then be in a mismatched state which means if an
instruction was using 16bit addressing + modrm + literal at /that/ point
the number of literal bytes remaining would be calculated as a negative.
This didn't actually break things since instructions that have modrm +
literal and can safely use 16bit addressing without breaking in a 32bit
environment is impossible on Linux. Due to the inability to map a memory
range in 16bit range.

Fixes 64bit ELF loading when LLVM ASAN is used
...
Instead of hardcoding 64bit dynamic ELF files to 0x1'0000'0000 we
instead calculate the size of the ELF in memory. Then allocate the
ELF base up front.
LLVM ASAN steals a large amount of virtual memory space that intersected
with the original hardcoded range which caused memory allocations to
fail.
