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.

Move tree navigation to a new Path class that doesn't have to be a template.

The path also holds a reference to the root node, and that allows important
iterator accessors like start() and stop() to have no conditional code. (When
the compiler is clever enough to remove it.)

Remove explicit uses of -emit-llvm, the test infrastructure adds it
automatically.  Use -S with llvm-gcc rather than -c, so tests can
work when llvm-gcc is really dragonegg (which can output IR with -S
but not -c).  Yes, dragonegg supports objective-c++ (poorly though).

Judging from the comment, the system assembler is supposed to assemble
the output of this test.  Since it was producing bitcode, that clearly
wasn't happening!  Have it produce target assembler and assemble that
instead.

Using LLVMCC_EMITIR_FLAG rather than hard-coding -emit-llvm

to everyone else).

It seems inconsistent to have LLVMCC_EMITIR_FLAG and
LLVMGCC_DISABLEOPT_FLAGS, one with CC in it, the other
with GCC.  Rename LLVMGCC_DISABLEOPT_FLAGS to
LLVMCC_DISABLEOPT_FLAGS.
