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.

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.

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.

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.
