[RFC 0/1] Stack trace support in X64 exception handling

[Paulo Alcantara <pcacjr@zytor.com>]

Hi,

This series adds stack trace support during a X64 CPU exception.

Informations like back trace, stack contents and image module names
(that were part of the call stack) will be dumped out.

We already have such support in ARM/AArch64 (IIRC) exception handling
(thanks to Ard), and then I thought we'd also deserve it in X64 and
IA-32 platforms.

What do you think guys?

BTW, I've tested this only with OVMF (X64 only), using:
  - gcc-6.3.0, GCC5, NOOPT

Any other tests  would be really appreciable.

Thanks!
Paulo
