Fix a long-standing bug and misfeature of the disassembler: when dealing with a
...
stripped .bc file, it didn't make any attempt to try to reuse anonymous types.
This causes an amazing type explosion due to types getting duplicated everywhere
they are referenced and other problems.
This also caused correctness issues, because opaque types are unique for each time
they are uttered in the file. This means that stripping a .bc file could produce
a .ll file that could not be assembled (e.g. 2009-02-28-StripOpaqueName.ll).
This patch fixes both of these issues.

Fix big-endian codegen bug. We're splitting up
...
overly long ints, e.g. i96, into pieces at PHIs
and the nodes that feed into them; however big-endian
reverses the order of the pieces (for some reason), and
wasn't doing it the same way on both sides, so
the pieces didn't match and runtime failures ensued.
Fixes 188.ammp and sqlite3 on ppc32.

Clean up dwarf writer, part 1. This eliminated the horrible recursive getGlobalVariablesUsing and replaced it something readable. It eliminated use of slow UniqueVector and replaced it with StringMap, SmallVector, and DenseMap, etc. It also fixed some non-deterministic behavior.

Overhaul my earlier submission due to feedback. It's a large patch, but most of

them are generic changes.
- Use the "fast" flag that's already being passed into the asm printers instead
of shoving it into the DwarfWriter.

machine function when calling "runOnMachineFunction" in the asm printers.

need to investigate still.

now always using zero-extensions is preferable.
