Bug 19176 – Dmd crashes because of __traits(getUnitTests)

Test case: ``` void main() { __traits(getUnitTests, foo); } template foo() { static if(true) { enum bar; } else { enum bar; } } ``` Results in: ``` $ dmd -v -c -unittest foo.d predefs DigitalMars Posix linux ELFv1 LittleEndian D_Version2 all D_SIMD D_InlineAsm_X86_64 X86_64 CRuntime_Glibc D_LP64 D_PIC unittest assert D_HardFloat binary dmd version v2.081.2 config /etc/dmd.conf DFLAGS -I/usr/include/dlang/dmd -L-L/usr/lib -L--export-dynamic -fPIC parse foo importall foo import object (/usr/include/dlang/dmd/object.d) semantic foo entry main foo.d semantic2 foo semantic3 foo foo.d(6): Error: static if conditional cannot be at global scope zsh: segmentation fault (core dumped) dmd -v -c -unittest foo.d ```
