Jian J Wang 7c7c8190d3 UefiCpuPkg/CpuDxe: change level of DEBUG message
BZ#1127: https://bugzilla.tianocore.org/show_bug.cgi?id=1127

It's reported the debug message in CpuDxe driver is quite annoying in
boot and shell, and slow down the boot process. To solve this issue,
this patch changes the DEBUG_INFO to DEBUG_VERBOSE. On a typical Intel
real platform, at least 16s boot time can be saved.

Jian J Wang 147fd35c3e UefiCpuPkg/CpuDxe: Enable protection for newly added page table
One of the functionalities of CpuDxe is to update memory paging attributes.
If page table protection is applied, it must be disabled temporarily before
any attributes update and enabled again afterwards.

This patch makes use of the same way as DxeIpl to allocate page table memory
from reserved memory pool, which helps to reduce potential "split" operation
and recursive calling of SetMemorySpaceAttributes().

Laszlo (lersek@redhat.com) did a regression test on QEMU virtual platform with
one middle version of this series patch. The details can be found at

 https://lists.01.org/pipermail/edk2-devel/2017-December/018625.html

There're a few changes after his work.

Jian J Wang c46bced224 UefiCpuPkg/CpuDxe: Fix assert issue on IA32 platform
This patch is to fix an assert issue during booting IA32 platforms
such as OvmfIa32 or Quark. This issue is caused by trying to access
page table on a platform without page table. A check is added to
avoid the assert.

jljusten 557b970a2f UefiCpuPkg CpuDxe: Fix bug with CPU Arch RegisterInterruptHandler
The change in r10765 introduced an issue where inherited interrupt
handlers would override the driver's RegisterInterruptHandler
functionality.

DUET installs a IDT with 256 entries early in it's boot.  Therefore,
no interrupt handlers could be installed with DUET while using
UefiCpuPkg/CpuDxe (instead of DuetPkg/CpuDxe).

This change forces the IDT to be modified when RegisterInterruptHandler
is called to ensure the UEFI handler will be installed properly.
