inline function, software simulation passed, HLS failed

[linghaosong]

If we invoke an inline function by mistake, it can be compiled and pass the software emulation, but gets failed when HLS. Can you add a check at compile time?

@syiming who found this issue.

Interesting... so it looks like HLS does not like functions with the inline specifier being the top.

@linghaosong @syiming This won't be trivially doable during software simulation (compilation or runtime), but we could add a check in tapacc and emit a readable error before running HLS. This should be straight-forward.
