When annotating "lines" starting with ":", clang-format would segfault.
This could actually happen in valid code, e.g.
  #define A :

we weren't differntiating floating-point zeroinitializers from other zero-initializers)
which was causing problems for code relying upon a + (+0.0f) to, eg, flush denormals to
0. Make the scalar and vector cases have the same behaviour.

Unfortunately the previous fix for inserting waits for unordered
defines wasn't sufficient, cause it's possible that even ordered
defines are only partially used (or not used at all).

Clang does not like classes with virtual functions but w/o virtual dtor.
Go does not like libstdc++ (operator delete).

[asan] when creating string constants, set unnamed_attr and align 1 so that equal strings are merged by the linker. Observed up to 1% binary size reduction. Thanks to Anton Korobeynikov for the suggestion

MinGW is almost completely compatible to MSVC, with the exception of the _tls_array global not being available.

Patch by David Nadlinger!

The linker sorts the .tls$<xyz> sections by name, and we need
to make sure any extra sections we produce (e.g. for weak globals) 
always end up between .tls$AAA and .tls$ZZZ, even if the name 
starts with e.g. an underscore.

[asan] while generating the description of a global variable, emit the module name in a separate field, thus not duplicating this information if every description. This decreases the binary size (observed up to 3%). https://code.google.com/p/address-sanitizer/issues/detail?id=168 . This changes the asan API version. llvm-part
