5% - no slowdowns observed.

tools/Makefile: Don't look into $(TARGET_OS), but $(HOST_OS), to inspect availability of loadable module!

The last commit made run.build.step.test_llvm_1 to fail.

%llvmshlibdir should be 'bin' on Cygming.

uninitialized. The warning is terrible, has incorrect source locations, and has
a huge false positive rate such as *all* of these.

If anyone has a better solution, please let me know. Alternatively, I'll
happily add -Wno-uninitialized to the -Werror build mode. Maybe I can even do
it *only* when building with GCC instead of Clang.

bugpoint-passes would be built with ENABLE_SHARED=1.
You could try building gold on Cygming, though, it would fail.

Sometimes std::copy can become a memmove call, and that is not a good idea when
copying relatively few bytes as we are doing. We also get a small win by
changing two loops into one.

We always disallowed overlapping inserts with different values, and this makes
the insertion code smaller and faster.

If an overwriting insert is needed, it can be added as a separate method that
trims any existing intervals before inserting. The immediate use cases for
IntervalMap don't need this - they only use disjoint insertions.

instructions.  I choose to handle this with an asmparser hack,
though it could be handled by changing all the instruction definitions
to allow be "setneb" instead of "setne".  The asm parser hack is
better in this case, because we want the disassembler to produce
setne, not setneb.

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

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