Reland "[NFC][lldb] Speed up lookup of shared modules" (229d860) (#152607)
The previous commit was reverted because it broke a test on the bots.
Original commit message:
By profiling LLDB debugging a Swift application without a dSYM and a
large amount of .o files, I identified that querying shared modules was
the biggest bottleneck when running "frame variable", and Clang types
need to be searched.
One of the reasons for that slowness is that the shared module list can
can grow very large, and the search through it is O(n).
To solve this issue, this patch adds a new hashmap to the shared module
list whose key is the name of the module, and the value is all the
modules that share that name. This should speed up any search where the
query contains the module name.
