As per the code comment added in this commit the nir produced from
glsl to nir doesn't always keep function declarations before the
code that calls them e.g. calls from within other function
implementations. The change in this commit works around this problem by
first cloning all function declarations in a first pass, then cloning
the implementations in a second pass once we have filled the remap
table.
