whitequark [Mon, 2 Nov 2020 19:18:56 +0000 (19:18 +0000)]
cxxrtl: run `hierarchy -auto-top` if no top module is present.
In most cases, a CXXRTL simulation would use a top module, either
because this module serves as an entry point to the CXXRTL C API,
or because the outputs of a top module are unbuffered, improving
performance. Taking this into account, the CXXRTL backend now runs
`hierarchy -auto-top` if there is no top module. For the few cases
where this behavior is unwanted, it now accepts a `-nohierarchy`
option.
Fixes #2373.

xilinx: Fix attributes_test.ys
This test pretty much passes by accident — the `prep` command runs
memory_collect without memory_dff first, which prevents merging read

The attribute setting didn't actually work because it was set on the
containing module instead of the actual memory.
