[WIP] NFData Instance for AsteriusModule

[gkaracha]

• Add NFData instances for most datatypes in Asterius.Types, and
• Utilize the new NFData instances to fully evaluate the shrinked AsteriusModule produced by Asterius.Resolve.linkStart.

After this PR is merged, we should be able to do a little better, by parallelizing AsteriusModules evaluation (see #621).

Currently ticks seem to go slightly down:

Since we are monitoring performance more closely these days, here is a quick comparison:

• ahc (before: 282 ticks, after: 253 ticks)
• ahc-ld (before: 9943 ticks, after: 10307 ticks)
• ahc-link (before: 45824 ticks, after: 45389 ticks)

The small cost in ahc-ld is acceptable, since the profile report now contains the cost center of evaluating the post gc-sections module.
