Chris Lattner 42e31dfd4f fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which 
is substantially different than a(b|c)d.  Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

they thought they were, because alternation was expanding
wrong in {{}}'s.

Jakob Stoklund Olesen f4afdfc501 Build the Hopfield network incrementally when splitting global live ranges. 
It is common for large live ranges to have few basic blocks with register uses
and many live-through blocks without any uses. This approach grows the Hopfield
network incrementally around the use blocks, completely avoiding checking
interference for some through blocks.

Jakob Stoklund Olesen 9d29cbad32 Precompute interference for neighbor blocks as long as there is no interference. 
This doesn't require seeking in the live interval union, so it is very cheap.

Devang Patel fb6e8d6554 Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array. 
If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.

Jim Grosbach 5b03a3a59a Mark hasExtraDefRegAllocReq=1 on LDRD. 
The previous cleanup of LDRD got overzealous and removed it, causing post-RA
scheduling to get overzealous in breaking antidependencies and invalidate these instructions. Hilarity and invalid assembly ensued.

Bill Wendling 44dcfd3625 Replace the old algorithm that emitted the "print the alias for an instruction" 
with the newer, cleaner model. It uses the IAPrinter class to hold the
information that is needed to match an instruction with its alias. This also
takes into account the available features of the platform.

There is one bit of ugliness. The way the logic determines if a pattern is
unique is O(N**2), which is gross. But in reality, the number of items it's
checking against isn't large. So while it's N**2, it shouldn't be a massive time
sink.
