[PowerPC][NFC] Pre-commit a test case for upcoming patch

[SampleProfile] Use LazyCallGraph instead of CallGraph

The function order in some tests had to be changed because they relied on ordering of functions returned in an SCC which is consistent but unspecified.

[LSR] Fix wrapping bug in lsr-term-fold logic

The existing logic was unsound, in two ways.

First, due to wrapping on the trip count computation, it could compute a value which convert a loop which exiting on iteration 256, to one which exited at 255. (With i8 trip counts.)

Second, it allowed rewriting when the trip count implies wrapping around the alternate IV. As a trivial example, it allowed rewriting an i128 exit test in terms of an i64 IV. This is obviously wrong.

Note that the test change is fairly minimal - i.e. only the targeted test - but that's only because I precommitted a change which switched the test from 32 to 64 bit pointers. For 32 bit point architectures with 32 bit primary inductions, this transform is almost always unsound to perform.

Changes to `SCFFuseProducerOfSliceResult` to also return the operations created during fusion.

This is follow up to https://reviews.llvm.org/D145133 that allows
propogating information about ops that are fused back to the caller.

[JITLink][ELF][AArch64] Add support for ELF R_AARCH64_ABS32 relocation.

This relocation is commonly used in debug sections. Failure to handle it caused
the test failure in https://lab.llvm.org/buildbot/#/builders/197/builds/4272,
which forced the reversion, in f721fcb6ed0, of 57aeb305460 ("[JITLink][ELF]
Don't skip debug info sections by default"). This fix should allow us to
re-land 57aeb305460.

[libc][bazel] add targets for sprintf

The bazel build is currently overlay mode only, so the FILE functions

Fix a problem with "watchpoint triggers before" watchpoint handling.

We need to step the watchpoint instruction in these cases, but the
when we queued the ThreadPlanStepOverWatchpoint to do this, we didn't
make it a Controlling plan.  So if you are stepping, this plan returns as
though it were a utility plan, and the stepping plan keeps going.

This only partially fixes the problem on Darwin; there's another bug
with reporting a watchpoint when we're instruction single stepping over
an instruction that triggers a watchpoint.  The kernel reports the
"single step completed" but not the watchpoint hit.  So this commit
also refactors the test into a part that works (at least on Darwin) and
a part that still fails.

We may have to adjust the test result expectations for other systems after
this fix.
