Update passes to handle function declarations (#4599)
Spirv-opt has not had to handle module with function declarations.  This
lead many passes to assume that every function has a body.  This is not
always true.  This commit will modify a number of passes to handle
function declarations.

Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/4443
