[PowerPC] Do not merge TLS constants within PPCMergeStringPool.cpp (#94059)
This patch prevents thread-local constants to be merged within
Merge commit cf721e29c6a3 from llvm git (by Amy Kwan):
[PowerPC] Do not merge TLS constants within PPCMergeStringPool.cpp (#94059)
This patch prevents thread-local constants to be merged within
PPCMergeStringPool.cpp.
The PPCMergeStringPool pass primarily merges non-thread-local constants
together, and thread-local constants should not be mixed together with
other (non-thread-local) constants. In the event that thread-local and
other non-thread-local constants are pooled together, the
llvm.threadlocal.address intrinsic can fail as it expects its argument
to be a thread-local global value, but the merged string structure
created by the PPCMergeStringPool pass is not thread-local as a whole.
This fixes an error "llvm.threadlocal.address first argument must be a
GlobalValue" when building the math/nauty port on PowerPC architectures.

Merge commit 9f85bc834b07 from llvm-project (by Nikita Popov):
[PPCMergeStringPool] Only replace constant once (#92996)
In #88846 I changed this code to use RAUW to perform the replacement
instead of manual updates -- but kept the outer loop, which means we try
to perform RAUW once per user. However, some of the users might be freed
by the RAUW operation, resulting in use-after-free.
The case where this happens is constant users where the replacement
might result in the destruction of the original constant.
Fixes https://github.com/llvm/llvm-project/issues/92991.
This fixes a possible crash when building crypto/openssh/sshkey.c for
PowerPC targets.
