[Mesa-dev] [PATCH] nir/builder: Don't use designated initializers

[Jason Ekstrand]

Designated initializers are not allowed in C++ (not even C++11).  Since
nir_lower_samplers is now using nir_builder, and nir_lower_samplers is in
C++, this breaks the build on some compilers.  Aparently, GCC 5 allows it
in some limited extent because mesa still builds on my system without this
patch.
