[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.

[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.

[X86] Add slow div64 tuning flag to Nehalem target (#91129)
This appears to have been missed because later cpus don't inherit from Nehalem tuning much.
Noticed while cleaning up for #90985
Merge commit 8b400de79eff from llvm-project (by Simon Pilgrim):
[X86] Enable TuningSlowDivide64 on Barcelona/Bobcat/Bulldozer/Ryzen Families (#91277)
Despite most AMD cpus having a lower latency for i64 divisions that converge early, we are still better off testing for values representable as i32 and performing a i32 division if possible.
All AMD cpus appear to have been missed when we added the "idivq-to-divl" attribute - this patch now matches Intel cpu behaviour (and the x86-64/v2/3/4 levels).
Unfortunately the difference in code scheduling means I've had to stop using the update_llc_test_checks script and just use old-fashioned CHECK-DAG checks for divl/divq pairs.
Fixes #90985
This fixes possibly worse runtime performance on AMD Zen hardware, when
using -march=znver4 (or any other znver), as opposed to -march=x86-64-v4
or the baseline -march=x86-64. A similar fix is applied for Nehalem.

them for any type that can occur.

[PowerPC] Replace PPCISD::VABSD cases with generic ISD::ABDU(X,Y) node
A move towards using the generic ISD::ABDU nodes on more backends
Also support ISD::ABDS for v4i32 types using the existing signbit flip trick
PowerPC has a select(icmp_ugt(x,y),sub(x,y),sub(y,x)) -> abdu(x,y) combine that I intend to move to DAGCombiner in a future patch.
The ABS(SUB(X,Y)) -> PPCISD::VABSD(X,Y,1) v4i32 combine wasn't legal (https://alive2.llvm.org/ce/z/jc2hLU) - so I've removed it, having already added the legal sub nsw tests equivalent.
Differential Revision: https://reviews.llvm.org/D142313
This fixes a "Wasn't expecting to be able to lower this!" fatal error
when compiling graphics/opencv for PowerPC.
