Yonghong Song 51d6fa246d bpf: fix a bug in bpf-isel trunc-op optimization ...

In BPF backend, we try to optimize away redundant
trunc operations so that kernel verifier rewrite
remains valid. Previous implementation only works
for a single function.

This patch fixed the issue for multiple functions.
It clears internal map data structure before
performing optimization for each function.
