34ceb4db22 Transform (extractvalue (load P), ...) to (load (gep P, 0, ...)) if the load has no other uses, shrinking the load.

e89ada98a6 Add some dead stores to pacify my least favorite GCC warning: may be 
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.

08d55342e3 Don't use std::copy and std::copy_backward, run 10% faster. 
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.

5f456cda98 Disallow overlapping inserts, even when inserting the same value. 
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.

d8f717911d fix PR8686, accepting a 'b' suffix at the end of all the setcc 
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.
