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.

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.

Convert remaining 'DB' code to assembly code by:
* Move instruction immediate data labels to end of instruction
* Use strict keyword to make sure immediate data size is not optimized

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.

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.
