commit b08e7e270868a1c5492b8e288cd65a309ccead0c
Author: Martin Liska <mliska@suse.cz>

Remove conditional STATIC_ASSERT.
As we require a c++11 compliant compiler, the #if __cplusplus >= 201103L
conditional build is always true.
gcc/ChangeLog:
* basic-block.h (STATIC_ASSERT): Use normal STATIC_ASSERT.
* system.h (STATIC_ASSERT): Define always as static_assert.
