Current code always allocates/frees < 1MB WakeupBuffer for DxeMpLib
until ExitBootService, but the allocation may be failed at late
phase of the boot.
This patch is to always save/restore original WakeupBuffer for
DxeMpLib, it is aligned with the solution for PeiMpLib at
9293d6e42e, then AllocateResetVector()
and FreeResetVector() will be common and moved to MpLib.c.
Only difference is GetWakeupBuffer() that will be in PeiMpLib or
DxeMpLib respectively.

Fix NASM compatibility issues with XCODE5 tool chain.
The XCODE5 tool chain for X64 builds using PIE (Position
Independent Executable). For most assembly sources using
PIE mode does not cause any issues.
However, if assembly code is copied to a different address
(such as AP startup code in the MpInitLib), then the
X64 assembly source must be implemented to be compatible
with PIE mode that uses RIP relative addressing.
The specific changes in this patch are:
* Use LEA instruction instead of MOV instruction to lookup
the addresses of functions.
* The assembly function RendezvousFunnelProc() is copied
below 1MB so it can be executed as part of the MpInitLib
AP startup sequence. RendezvousFunnelProc() calls the
external function InitializeFloatingPointUnits(). The
absolute address of InitializeFloatingPointUnits() is
added to the MP_CPU_EXCHANGE_INFO structure that is passed
to RendezvousFunnelProc().
