This makes the diagnostic output order deterministic.
1) This makes order of text diagnostics consistent from run to run.
2) Also resulted in different bugs being reported (from one run to
another) with plist-html output.

This prevents us from treating the issues from different files with the
same function names and same offsets as the same.
The issue identifier now includes the file name. Also added a way to
strip off the root directories form the source file names.

The height on an instruction is the minimum number of cycles from the
instruction is issued to the end of the trace. Heights are computed for
all instructions in and below the trace center block.
The method for computing heights is different from the depth
computation. As we visit instructions in the trace bottom-up, heights of
used instructions are pushed upwards. This way, we avoid scanning long
use lists, looking for uses in the current trace.
At each basic block boundary, a list of live-in registers and their
minimum heights is saved in the trace block info. These live-in lists
are used when restarting depth computations on a trace that
converges with an already computed trace. They will also be used to
accurately compute the critical path length.

keep a shared pointer to their disassembler. This
is important for the LLVM-C disassembler because
it needs to lock its parent in order to disassemble
itself.
This means that every interface that returned a
Disassembler* needs to return a DisassemblerSP, so
that the instructions and any external owners share
the same reference count on the object. I changed
all clients to use this shared pointer, which also
plugged a few leaks.

TinyPtrVector. With these, it is sufficiently functional for my more
normal / pedestrian uses.
I've not included some r-value reference stuff here because the value
type for a TinyPtrVector is, necessarily, just a pointer.
I've added tests that cover the basic behavior of these routines, but
they aren't as comprehensive as I'd like. In particular, they don't
really test the iterator semantics as thoroughly as they should. Maybe
some brave soul will feel enterprising and flesh them out. ;]

don't explode if the offset we get is zero. This can happen if
you have an empty virtual base class.
While I'm at it, remove an unnecessary block from the IR-generation
of the null-check, mark the eventual GEP as inbounds, and generally
prettify.

Since the llvm::sys::fs::map_file_pages() support function it relies on
is not yet implemented on Windows, the unit tests for FileOutputBuffer
are currently conditionalized to run only on unix.

No new test case is added.
This patch makes test JITTest.FunctionIsRecompiledAndRelinked pass on mips
platform.
