fix a fairly serious oversight with switch formation from
...
or'd conditions. Previously we'd compile something like this:
int crud (unsigned char c) {
return c == 62 || c == 34 || c == 92;
}
into:
switch i8 %c, label %lor.rhs [
i8 62, label %lor.end
i8 34, label %lor.end
]
lor.rhs: ; preds = %entry
%cmp8 = icmp eq i8 %c, 92
br label %lor.end
lor.end: ; preds = %entry, %entry, %lor.rhs
%0 = phi i1 [ true, %entry ], [ %cmp8, %lor.rhs ], [ true, %entry ]
%lor.ext = zext i1 %0 to i32
ret i32 %lor.ext
which failed to merge the compare-with-92 into the switch. With this patch
we simplify this all the way to:
switch i8 %c, label %lor.rhs [
i8 62, label %lor.end
i8 34, label %lor.end
i8 92, label %lor.end
]
lor.rhs: ; preds = %entry
br label %lor.end
lor.end: ; preds = %entry, %entry, %entry, %lor.rhs
%0 = phi i1 [ true, %entry ], [ false, %lor.rhs ], [ true, %entry ], [ true, %entry ]
%lor.ext = zext i1 %0 to i32
ret i32 %lor.ext
which is much better for codegen's switch lowering stuff. This kicks in 33 times
on 176.gcc (for example) cutting 103 instructions off the generated code.

simplifycfg to do this xform, now we can just check blocks ending with

block, which should be a significant compile-time perf win on functions
with lots of edges. No functionality change.

Reduce the number of builtin operator overload candidates added in certain
...
cases. First, omit all builtin overloads when no non-record type is in the set
of candidate types. Second, avoid arithmetic type overloads for non-arithmetic
or enumeral types (counting vector types as arithmetic due to Clang
extensions). When heavily using constructs such as STL's '<<' based stream
logging, this can have a significant impact. One logging-heavy test case's
compile time dropped by 10% with this. Self-host shows 1-2% improvement in
compile time, but that's likely in the noise.

Fixed a multi-threaded race condition that could happen when communication classes are shutting down. We currently don't protect communication connection classes against multi-threaded access. The connection is stored in the lldb_private::Communication.m_connection_ap auto_ptr member. We either need to add protections when accessing this class or not let anything racy occur. With this fix, we are doing the latter.

Move the functionality to mark all vtables of key functions as used within
...
a translation unit to the ActOnEndOfTranslationUnit function instead of doing
it at the start of DefineUsedVTables. The latter is now called *recursively*
during template instantiation, which causes an absolutely insane number of
walks of every record decl in the translation unit.
After this patch, an extremely template instantiation heavy test case's compile
time drops by 10x, and we see between 15% and 20% improvement in average
compile times across a project. This is just recovering a regression, it
doesn't make anything faster than it was several weeks ago.

Fixed an issue where the macosx dynamic loader, on the first shared library loaded notification, wasn't properly removing shared libraries from the target that didn't get loaded. This usually happens when a different shared library is loaded in place of another due to DYLD_LIBRARY_PATH or DYLD_FRAMEWORK_PATH environment variables. We now properly remove any images that didn't make it into the executable.
