happily add -Wno-uninitialized to the -Werror build mode. Maybe I can even do

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120265 91177308-0d34-0410-b5e6-96231b3b80d8

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.

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

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.

Second attempt at fixing the performance regressions introduced
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.

ADT/InMemoryStruct: Add an experimental helper class intended for use in
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.

Add NEON VLD1-dup instructions (load 1 element to all lanes).

Fix incorrect scheduling itineraries for NEON vld1/vst1 instructions.
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.

MC/Mach-O: Switch to using MachOFormat.h.
 - I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

MC/Mach-O: Introduce Object/MachOFormat for describing purely platform / machine
independent information on the Mach object format, and move some stuff from
MachObjectWriter.cpp there.

BitVector tweaks.

- Double the vector's capacity when growing to avoid unneeccesary reallocation.
- Do the reallocation with realloc(3) which can expand the memory in place.

unittests/JITTests: Don't use --export-dynamic but --export-all-symbols on cygming.

GNU ld/PECOFF accepts but ignores them below;
  --version-script
  --export-dynamic
  --rpath

FIXME: autoconf should be aware of them.

test/site.exp.in: Add "emitir", for now, fixing up r120156. CMake depends on site.exp.in, though, "emitir" might be unused.
