Built from the following source:
void f1();
__attribute__((always_inline)) inline void f2() { f1(); }
void f3() { f2(); }
Compiled to assembly with clang, modified the skeleton CU to remove the
high/low pc (& update the CU length field and abbrev to match) & then
compile/objcopy to make the .o and .dwo.
