show error if run with Xcode 4 or lower.

We're dropping support for Xcode 4.
should show build #error if Xcode is < 5.0.

We're dropping support for the Xcode 4 toolchain.
adding a Run Script to verify libs are built as Universal

... and fixing the cases for otest-query*-osx where the lib was only
built as x86_64 in debug mode.
switching xctool to use the clang-as-ios-dylib workaround.

We can now retire the iOS-Simulator-Dylib.xcconfig stuff.
remove support for running GC-enabled tests.

Xcode 5.1 will drop support for building GC-enabled binaries, so we
should drop it in Xcode, too.
fix leak in ArchiveAction
when overriding test names, override `name` and `description`.

should fix #273
fix 'No matching SDK for arch i386' build error.

Oops - there was a bug here.  i386 is a valid arch for all SDKs.  Fixes
fix bug where the 'analyze' would try to parse results from non-plists.

For some reason, `-[NSRegularExpression firstMatchInString:options:range:]`
has begun returning nil when there's no match.  This didn't use to
happen, and the docs don't suggest it would happen... it could be a
legit apple bug.

This silences the `Old-style plist parser: missing semicolon in
dictionary on line 2. Parsing will be abandoned.` warnings we've seen.
use xcodebuild's `analyze` action insteaad of RUN_CLANG_STATIC_ANALYZER=YES

Now with Xcode 5, we don't have to use the RUN_CLANG_STATIC_ANALYZER=YES
hack.
