[WebAssembly] Ignore explicit section names for functions
WebAssembly doesn't support more than one function per section
and we rely on function sections being unique. This change ignores
the section provided by the function to avoid two functions being
in the same section.
Without this change the object writer produces the following
error for this test:
LLVM ERROR: section already has a defining function: baz
