util: Build m5 with -no-pie flag


Added -no-pie flag to link /util/m5 to support newer versions of GCC
that enable PIE by default. Tested for backwards compatibility with GCC
4.3, which, only warns for the unrecognized flag.

util: Do not use $(PWD) in Makefiles

644e8cdf5ee7 ("util: Move the m5ops.h file to a shared directory")
added include/ to the include path for m5 Makefiles, based on
$(PWD): $(PWD)/../../include.

Unfortunately, this breaks when using `make -C <path>`, as -C does
not move PWD accordingly. The fix is simply to remove $(PWD), as a
relative path is just fine here.

util: Implement Lua module for m5ops.

This module allows m5ops to be executed in Lua programs.
To compile it (in util/m5):
The following command generates Lua moduel, gem5OpLua.so.

make -f Makefile.<arch> gem5OpLua.so

To use it:
First, put gem5OpLua.so in Lua library search path.
Then, import the module and execute the m5op function.

Example usage, creating a checkpoint.

m5 = require("gem5OpLua")
m5.do_checkpoint(0, 0)

util: Move the m5ops.h file to a shared directory

The header file m5ops.h contains a list of constants that should be
shared between the simulator and utilities. Move this header file to a
new top-level directory for shared files and rename constants to make
them suitable for inclusion in the main simulator.

The structure of the shared include directory is as follows:

include/gem5: Files that can be included from C code.
include/gem5/asm: Files that can be included from assembly code.
asm/generic/: Files that aren't guest ISA specific
asm/${isa}/: Files that are guest ISA specific

x86: Add support for m5ops through a memory mapped interface

In order to support m5ops in virtualized environments, we need to use
a memory mapped interface. This changeset adds support for that by
reserving 0xFFFF0000-0xFFFFFFFF and mapping those to the generic IPR
interface for m5ops. The mapping is done in the
X86ISA::TLB::finalizePhysical() which means that it just works for all
of the CPU models, including virtualized ones.
