Fix non-determinism in DAGISel emitter.
- This manifested as non-determinism in the .inc output in rare cases (when two
distinct patterns ended up being equivalent, which is rather rare). That
meant the pattern matching was non-deterministic, which could eventually mean
the code generator selected different instructions based on the arch.
- It's probably worth making the DAGISel ensure a total ordering (or force the
user to), but the simple fix here is to totally order the Record* maps based
on a unique ID.
- PR4672, PR4711.

Add simple cost model to perfect shuffle. Currently we're doing just greedy search for cost instead of (proper) dynamic programming approach.2009-08-21T12:41:03ZAnton Korobeynikovasl@math.spbu.ru2009-08-21T12:41:03Zurn:sha1:c9d44f0d9c609f86e13fbf2e27165b663f94efe3

try to use i686-darwin to build for arm-eabi, you'll quickly run into
several false assumptions that the target OS must be the same as the
host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to
help builds like "make check" and the test-suite able to cross
compile. Along the way a target of *-unknown-eabi is defined as
"Freestanding" so that TARGET_OS checks have something to work with.

Extend the instruction itinerary model to include the ability to indicate the def and use cycle for each operand. This additional information is optional, so existing itineraries do not need to be changed.2009-08-17T16:02:57ZDavid Goodwindavid_goodwin@apple.com2009-08-17T16:02:57Zurn:sha1:fac8541dd40e01aa2b52962516f9ae67c99720cc

just remove the argument and replace it with 1.
