pkg/codesearch: reduce memory consumption when building index
With all references in the index, it become quite big.
Merge and dedup the resulting index on the fly.
Also intern all strings b/c there are tons of duplicates.
This also removes unnecessary duplicates (effectively ODR violations in the kernel)
due to use of BUILD_BUG_ON. The macro produces different function calls
in different translations units, so the same function may contain
__compiletime_assert_N1 call in one TU and __compiletime_assert_N2 in another.
Over this reduces resource consumption of index building from:
time:296.11s user:16993.71s sys:6661.03s memory:82707MB
to:
time:194.28s user:16860.01s sys:6647.01s memory: 3243MB
25x reduction in memory consumption.
