Revert "cg_llvm: fewer_names in uncached_llvm_type"

[davidtwco]

Fixes #76213 and fixes #79564.

This PR temporarily reverts commit fa01ce8 from #76030 to until the root issue can be resolved. Requested in t-compiler meeting.

Note: I was seeing some failing debuginfo-gdb tests locally but I wasn't sure if they were spurious.
