This is obviosly right but I don't see how to do this with proper vector
iterators without building a horrible mess of workarounds.

SelectionDAGBuilder: When emitting small compare chains for switches order them by using edge weights.

SimplifyCFG tends to form a lot of 2-3 case switches when merging branches. Move
the most likely condition to the front so it is checked first and the others can
be skipped. This is currently not as effective as it could be because SimplifyCFG
destroys profiling metadata when merging branches and switches. Merging branch
weight metadata is tricky though.

This code touches at most 3 cases so I didn't use a proper sorting algorithm.

A local std::string was being filled in and then the function would return "s.c_str()".
A local StreamString (which contains a std::string) was being filled in, and essentially also returning the c string from the std::string, though it was in a the StreamString class.

The fix was to not do this by passing a stream object into StringList::Join() and fix the "arch_helper()" function to do what it should: cache the result in a global.

then it doesn't alter the instructions composing it, however it would continue
to move the instructions to just before the expression root.  Ensure it doesn't
move them either, so now it really does nothing if there is nothing to do.  That
commit also ensured that nsw etc flags weren't cleared if the expression was not
being changed.  Tweak this a bit so that it doesn't clear flags on the initial
part of a computation either if that part didn't change but later bits did.

-Wsometimes-uninitialized diagnostics to make it clearer that the cause
of the issue may be a condition which must always evaluate to true or
false, rather than an uninitialized variable.

To emphasize this, add a new note with a fixit which removes the
impossible condition or replaces it with a constant.

Also, downgrade the diagnostic from -Wsometimes-uninitialized to
-Wconditional-uninitialized when it applies to a range-based for loop,
since the condition is not written explicitly in the code in that case.

are passed in. However, those arguments may be in a write-protected area, as far
as the runtime library is concerned. For instance, the data could be placed into
a 'linkedit' section, which isn't writable. Emit the code from
llvm_gcda_increment_indirect_counter directly into the function instead.

Note: The code for this is ugly, and can lead to bloat. We should look into
simplifying this code instead of having all of these branches.

The rules for emplace in map, multimap, unordered_map and unordered_multimap changed a while back and I'm just now updating to these new rules.  In a nutshell, you've got to know you're emplacing to a pair and use one of pair's constructors.  I made one extension:  If you want to emplace the key and default construct the mapped_type, you can just emplace(key), as opposed to emplace(piecewise_construct, forward_as_tuple(key), forward_as_tuple()).
