eabcdf3a34 MdePkg NASM Thunk16: Work around NASM 2.09.04 - 2.10rc1 bug 
Without this change, NASM 2.09.04 will hang with OVMF+CSM on both IA32
and X64.

Tested on OVMF+CSM on GCC49 with NASM 2.07, 2.09.04 and 2.11.

03e9db1575 MdePkg BaseLib NASM Thunk16: Initialize _16GdtrBase to 0 
Previously we were setting it to the start of the GDT in the UEFI
driver's copy of BaseLib. This address is irrelavent, since the C code
will initialize it to the cooresponding address after the Thunk16 code
has been placed in low memory.

Additionally, initializing this was causing a link error for the
XCLANG toolchain.

f6888eea46 MdePkg BaseLib NASM Thunk16: Use bits 16 for 16-bit code 
By using 'bits 16', we can write code for 16-bit use the actual
assembly syntax rather than 'DB' and sometimes writing code with
seemingly incorrect operands because we know it will run correctly
when the processor is running in 16-bit mode.

3c47fe65ed MdePkg: Fixed hang/reset in thunk code when building with GCC X64 
Reverted changes of data areas from .long back to .space 4.  This was done
because the size of .long is based off of .int and may vary.  Using a fixed size
is required because these values are for patching code.  Also note that .space
will automatically initialize the data to zero.  Not initializing all values to
zero was causing the hang/reset.
