This is the autoconf analog of r251201. I realize autoconf is
deprecated, but while it's in tree, it should at least be kept working.

Also add the deprecation message to configure.ac such that AutoRegen
actually picks ip up.

This adds part of the target info code, and adds modifications to
the build scripts so that AVR is recognized a supported, experimental
backend.

It does not include any AVR-specific code, just the bare sources required
for a backend to exist.

As per the very positive feedback from llvm-dev (http://lists.llvm.org/pipermail/llvm-dev/2015-November/092150.html), this commit officially deprecates the LLVM autoconf-based build system.

Anyone still using it should switch to CMake.

reorganize the conditional warning code based on compiler to be a bit
more obvious and inside a switch statement.

If we don't have sys/wait.h and we're on a unix system there's no way
that several of the llvm tools work at all. This includes clang.

Just remove the configure and cmake checks entirely - we'll get a
build error instead of building something broken now.

This is a followup from:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150323/268067.html

Upgrade instructions:
  $ mv llvm/include/llvm/Config/config.h ./config.h.BACKUP
  # copy the configure line from line 7 of llvm/config.log
  # (for example: `$ ./configure --no-create --no-recursion`)
  $ mkdir build
  $ cd build
  # run the configure line, but this time with '../llvm' at the beginning:
  $ ../llvm/configure --no-create --no-recursion

These warnings will soon be turned into hard errors after a week.  Speak up now
if this is going to be a problem for you.

FIXME: Should ENABLE_ABI_BREAKING_CHECKS be tri-state, "ON/OFF/blank"?
llvm-svn: 233801

Summary:
This patch is an attempt at making `DenseMapIterator`s "fail-fast".
Fail-fast iterators that have been invalidated due to insertion into
the host `DenseMap` deterministically trip an assert (in debug mode)
on access, instead of non-deterministically hitting memory corruption
issues.

Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are
predicated on `LLVM_ENABLE_ABI_BREAKING_CHECKS`.
`LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with
`LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake /
autoconf build system.

a CLANG_LIBDIR_SUFFIX variable. This is necessary before I can add
support for using that variable to CMake and the C++ code in Clang, and
the autoconf build system does all substitutions in the LLVM tree.

As mentioned before, I'm not planning to add actual multilib support to
the autoconf build, just enough stubs for it to keep playing nicely with
the CMake build once that one has support.

We were already requiring 2.5, which meant that people on old linux distros
had to upgrade anyway.

Requiring python 2.6 will make supporting 3.X easier as we can use the 3.X
exception syntax.

According to the discussion on llvmdev, there is not much value is requiring
just 2.6, we may as well just require 2.7.
