New walker to walk out of Instrimentation Frames FP
This patch contains a new walker that can walk out of inst frames in first party stackwalking mode.
For this to work, the emitter fixes located in pull request #451 must be applied. The walker itself creates
a Stackwalker frame based on the information saved by the emitter.

Fix for crashing on relocating at unistrumentable points
This fix is to address issue #455. When an unistrimentable point is selected for instrimenation
the behaviour Dyninst will now exhibit is the following:
1. InsertSnippet will return NULL if not in an insertion set and an illegal when parameter is used
2. If in an insertion set, InsertSnippet will return an object to the instrimentation. However when the set
is closed the insertion of that point will fail. It will either fail and continue to the next point (if
the insertion set closure is set to continue past errors) or roll back all prior insertions.
.

Log Message:
-----------
Separate debug info file issue fixed.
A DwarfFrameParser object was not being created in the case of separate
debug info file, because libdw does not create Dwarf handles to files
that contain only .eh_frame section without .debug_*. This was causing
AST variable node to assert because the local variables did not get
location list, since .eh_frame reference was never saved for lookup.
The solution was to create a DwarfFrameParser saving not only a possible
Dwarf handle but also an Elf reference, since the .eh_frame section will
be in the main stripped binary, while the Dwarf handle will point to
the separate debug file.

Fix for crashing on relocating at unistrumentable points. Fix checks whether a parameter is NULL or not, if it is NULL it does not perform the instrumentation.

Modification to x86 emitter to support SW out of inst frames.
This patch contains changes to the emitter to support first party stackwalking out of inst's frames. For inst frames to be walkable, instrimentation frames must be enabled.
The following changes were made to support this:
- Insertion of the previous SP into the stack at a known location (2 slots above the FP).
- Insertion of a special word into the stack such that stackwalker can easily identify that this frame is an inst frame (and to select the correct walker). BEEFDEAD is located at +1 slot away from FP.
- The poping of these values from the stack at frame teardown.
- Fixes to the emitter to use scratch registers where hard coded ones were present before.
Total performance impact of this patch is an extra 5 instruction. 3 on frame creation, 2 on destruction.

Minor fixes to FP Stack Unwinding through Inst Frames
Minor fixes to stack unwinding through instrimentation (applies to First Party stackwalker only).
Added additional comments to the walker to detail how it functions more clearly and what it is looking for to
accept a stack frame.
