Based on ArchType, Clang's driver can select a non-Clang compiler.
String parsing in Clang would have sufficed if it were only that,
however this change anticipates true llvm support.

Summary:
-march=bpf -> host endian
-march=bpf_le -> little endian
-match=bpf_be -> big endian
Test Plan:
v1 was tested by IBM s390 guys and appears to be working there.
It bit rots too fast here.

This allows us to extract version numbers from the environment.
getOSVersion is currently overloaded for that purpose, this allows us to
clean it up.

DenseMap has great support for catching invalidated iterators now so we can get
rid of this crude hack. Use after frees are covered by asan.

ArrayRef already has a SFINAE constructor which can construct ArrayRef<const T*> from ArrayRef<T*>.
This adds methods to do the same directly from SmallVector and std::vector. This avoids an intermediate step through the use of makeArrayRef.
Also update the users of this in LICM and SROA to remove the now unnecessary makeArrayRef call.

This version doesn't need begin/end but can instead just take a type which has begin/end methods.
Use this to replace an eligible foreach loop in LoopInfo found by David Blaikie in r237224.

Found by -Wpessimizing-move, no functional change. The APFloat and
PassManager change doesn't affect codegen as returning a by-value
argument will always result in a move.

Cache NumEntries locally, it's only used in an assert and using the member
variable prevents the compiler from eliminating the tombstone check for types
with trivial destructors. No functionality change intended.

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.

Modern libc's have an SSE version of memchr which is a lot faster than our
hand-rolled version. In the past I was reluctant to use it because Darwin's
memchr used a naive ridiculously slow implementation, but that has been fixed
some versions ago.
Should have zero functional impact.

Messed it up because I didn't realize there were two different iterators
here (& clearly didn't build any of this... ) - still seems easier to
just use the injected class name than introduce a self typedef.

This simplifies code quite a bit and brings the iterators closer to
C++'s iterator concept. No functional change intended.
