Add an option that allows one to "decode" the LSDA.

The LSDA is a bit difficult for the non-initiated to read. Even with comments,
it's not always clear what's going on. This wraps the ASM streamer in a class
that retains the LSDA and then emits a human-readable description of what's
going on in it.

So instead of having to make sense of:

Lexception1:

Jakob Stoklund Olesen [Thu, 16 Jun 2011 23:31:16 +0000 (23:31 +0000)]
Rename TRI::getAllocationOrder() to getRawAllocationOrder().

Also switch the return type to ArrayRef<unsigned> which works out nicely
for ARM's implementation of this function because of the clever ArrayRef
constructors.

The name change indicates that the returned allocation order may contain
reserved registers as has been the case for a while.

Don't use register classes larger than TLI->getRegClassFor(VT).

In Thumb mode we cannot handle GPR virtual registers, even though some
instructions can. When isel is lowering a CopyFromReg, it should limit
itself to subclasses of getRegClassFor(VT).
