Re: [Patch Ping] [RFC] Alias export patch

Sorry, that was not my day (or night).  I've fixed mem_attrs_htab_eq but
forgot about mem_attrs_htab_hash, and that slowed down expand
significantly.  After fixing this, I get on tramp3d-v4 with the options
Richard uses (-O2 -ffast-math -funroll-loops) as reported by
-ftime-report:

before the patch:
 TOTAL: 141.78             5.33           147.99            1675725 kB

after the patch:
 TOTAL: 142.90             5.09           148.64            1678628 kB

Running tramp3d with -n 50 gives 45.8 sec on a clean compiler and 45.1
sec on a patched compiler, which is probably within the noise.

On a collection of cc1-i-files compile-time difference is
~1%, and memory difference is ~0.2%.
