These iterators don't point anywhere, and they can't be compared to anything.
They are only good for assigning to.

Gentoo systems with multiple versions to pick up the newest one first. This is
especially important with Gentoo because some of the older versions are left on
systems in strange states.

This is a version of find() that always searches forwards and is faster for
local searches.

The op11_8 field is the same for all of them so put it in the instruction
classes instead of specifying it separately for each instruction.

Implement iterator::erase() in a simple version that erases nodes when they
become empty, but doesn't try to redistribute elements among siblings for better
packing.

Handle coalescing across leaf nodes which may require erasing entries.

Unittests need LLVM_BUILD_MODE to pick up each test.

Confirmed on CentOS5, Mingw, MSYS, and with possible configurations on VS8 and VS10.

by my recent GVN improvement.  Looking through a single layer of
PHI nodes when attempting to sink GEPs, we need to iteratively
look through arbitrary PHI nests.

situations where on the common path an API can return a pointer to some direct
memory, but which on an exceptional path may need to return a pointer to a
temporary struct.

I added these instructions recently but I have no idea where these "1"
values in the NextCycles field came from.  As far as I can tell now,
these instruction stages are clearly intended to overlap.
