01d53ec176 Add function for computing the edit distance of two arrays.
Accomplished by moving the body of StringRef::edit_distance into
a separate function that accepts two ArrayRefs, and making
StringRef::edit_distance a wrapper around the new function.

06accdade8 Switch a bunch of manual if-chains to use StringSwitch. Clean them up in
the process. Some of these are still a bit gross.

Still, this cuts 80 some lines out of this ridiculous file. ;]

58604cd944 Change default error_code ctor to a 'named ctor' so it's more self-documenting.
Unify default construction of error_code uses on this idiom so that users don't
feel compelled to make static globals for naming convenience. (unfortunately I
couldn't make the original ctor private as some APIs don't return their result,
instead using an out parameter (that makes sense to default construct) - which
is a bit of a pity. I did, however, find/fix some cases of unnecessary default
construction of error_code before I hit the unfixable cases)

4eebfb8b39 Remove static initializer from DataStream.cpp
If someone would prefer a clear name for the 'success' error_value we could
come up with one - potentially just a 'named constructor' style
'error_value::success()' to make this expression more self-documenting. If
I see this come up in other cases I'll certainly consider it.

One step along the way to resolving PR11944.

4aab4ab340 Remove SetWorkingDirectory from the Process interface. Nothing in LLVM
or Clang is using this, and it would be hard to use it correctly given
the thread hostility of the function. Also, it never checked the return
which is rather dangerous with chdir. If someone was in fact using this,
please let me know, as well as what the usecase actually is so that
I can add it back and make it more correct and secure to use. (That
said, it's never going to be "safe" per-se, but we could at least
document the risks...)

732f05c41f Add 'llvm_unreachable' to passify GCC's understanding of the constraints
of several newly un-defaulted switches. This also helps optimizers

assume as much.

8a86887ba3 use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJIT

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

08b73a30bb rename ENABLE_THREADS to LLVM_ENABLE_THREADS
Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

4d0a9ff365 Add support for tsan annotations (thread sanitizer, a valgrind-based tool).
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!
