of the dbg testsuite regressions.  I don't think this is
really the right fix; this change exposed an existing problem
upstream somewhere.

add a version of createLowerInvokePass that allows the client
to specify whether it wants "expensive" or "cheap" lowering.

otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

This fixes rdar://7908505

expression has computable loop evolution. While the operands of an
addrec are required to be loop-invariant, they're not required to 
dominate any part of the loop. This fixes PR6914.
