OpenACC default compute dimensions

This patch interrogates the target device to determine default gemotry at
runtime. This has the greatest difference on gang partitioning, where there's a
noticeable sawtooth in the relationship between number of gangs and execution
time. Picking the number of gangs as an exact multiple of num

Ah, I see. That's not obvious to me, so perhaps added documentation can be
expanded to explain that? (I now see that the plugin

Does it work when the user specifies one of the dimensions, so that references

Your patch broke bootstrap on ILP32 hosts, I'm testing following fix.
Supporting unsigned values from 0x8000U to 0xU only on LP64
