UBSAN rightly complains on `push_front`:
glslang/MachineIndependent/localintermediate.h:100:8: runtime error: load of value 160, which is not a valid value for type 'bool'
#0 in glslang::TCall::TCall(glslang::TCall&&) glslang/MachineIndependent/localintermediate.h:100

What happens here:
1. TCall's bool fields are not initialized on construction.
2. `push_front` move the `TCall` passed into it.
3. The move constructor copies unitialized bool, which may have an
out-of-range value.
What this fix does:
Calls `emplace_back` to ensure no copy/move constructor is called.
