This makes DwarfRegNum to accept list of numbers instead.
Added three different "flavours", but only slightly tested on x86-32/linux.
Please check another subtargets if possible,

different on different subtargets.  Use it for x86 f80.

nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

block that is being visited in the bitstream.  The client can also now
skip blocks before reading them, and query the current abbreviation number
as seen from the perspective of the Deserializer.  This allows the client
to be more interactive in the deserialization process (if they so choose).

instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().

If both parts of smul_lohi, etc. are used, don't simplify. If only one part is used, try simplify it.

Add the majority of machine-level critical edge breaking pass.  Most of this was written by Fernando, cleanup and updating to TOT by me.

This still needs a bit of work, particularly to handle jump tables properly.

Would somebody not on Darwin please make sure this
doesn't break anything.  Exception handling failures
would be the most likely symptom.
