6f7878a972 MdePkg/BaseLib: Preserve EBX register and fix stack offset to LinearAddress in AsmFlushCacheLine()
The value of EBX must be preserved to follow IA32 cdecl calling convention in the assembly 
implementation of AsmFlushCacheLine(). The CPUID instruction modifies the EBX register.
The EBX register value is saved onto the stack before CPUID and restored from the stack 
after CPUID.

The update to the inline assembly implementation of AsmFlushCacheLine() changed the location of the 
LinearAddress parameter value on the stack.  The hardcoded lookup using [esp + 4] is not correct.
Use the parameter name LinearAddress instead of the hard coded [esp + 4] stack location to prevent
this issue from occurring again if there are changes to the inline assembly in the future.

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.
