20531b3a6b [RelLookupTableConverter] Avoid querying TTI for declarations
This code queries TTI on a single function, which is considered to
be representative. This is a bit odd, but probably fine in practice.

However, I think we should at least avoid querying declarations,
which e.g. will generally lack target attributes, and for which
we don't seem to ever query TTI in other places.

36fdfaba19 [RelLookupTableConverter] Ensure that GV, GEP and load types match
This code could be generalized to be type-independent, but for now
just ensure that the same type constraints are enforced with opaque
pointers as with typed pointers.

e5a8af7a90 [Passes] Fix relative lookup table converter pass
This patch fixes the relative table converter pass for the lookup table
accesses that are resulted in an instruction sequence, where gep is not
immediately followed by a load, such as gep being hoisted outside the loop
or another instruction is inserted in between them. The fix inserts the
call to load.relative.instrinsic in the original place of load instead of gep.
Issue is reported by FreeBSD via https://bugs.freebsd.org/259921.

e96df3e531 [Passes] Add relative lookup table converter pass
Lookup tables generate non PIC-friendly code, which requires dynamic relocation as described in:
https://bugs.llvm.org/show_bug.cgi?id=45244

This patch adds a new pass that converts lookup tables to relative lookup tables to make them PIC-friendly.

This reverts commit 5178ffc7cf92527557ae16e86d0fa90d538c2a19.

Compiling `llvm-profdata` with a compiler build from this produces a
crashing binary.
