[LoopSink] Use MemorySSA with legacy pass manager
LoopSink with the legacy pass manager still uses AST, because we
can't compute MemorySSA conditionally. I think now that the legacy
pass manager will be removed soon(TM) we don't need to care about
compile-time impact here anymore. Additionally, since MemorySSA is
no longer eagerly optimized, the impact is actually not that high
anymore (~0.2% geomean regression on CTMark).
This just makes legacy PM and new PM behavior line up -- as a
followup I'll drop these options entirely and make MemorySSA use
mandatory.

Summary:

Reland: Expand existing loopsink testing to also test loopsinking using new pass manager and fix LICM bug.
Summary:
Expand existing loopsink testing to also test loopsinking using new pass
manager. Enable memoryssa for loopsink with new pass manager. This
combination exposed a bug that was previously fixed for loopsink
without memoryssa. When sinking an instruction into a loop, the source
block may not be part of the loop but still needs to be checked for
pointer invalidation. This is the fix for bugzilla #39695 (PR 54659)
expanded to also work with memoryssa.
Respond to review comments. Enable Memory SSA in legacy Loop Sink pass
under EnableMSSALoopDependency option control. Update tests accordingly.
Respond to review comments. Add options controlling whether memoryssa is
used for loop sink, defaulting to off. Expand testing based on these
options.
Respond to review comments. Properly indicated preserved analyses.
This relanding addresses a compile-time performance problem by moving
test for profile data earlier to avoid unnecessary computations.

Sink all InitializePasses.h includes
This file lists every pass in LLVM, and is included by Pass.h, which is
very popular. Every time we add, remove, or rename a pass in LLVM, it
caused lots of recompilation.
I found this fact by looking at this table, which is sorted by the
number of times a file was changed over the last 100,000 git commits
multiplied by the number of object files that depend on it in the
current checkout:

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[LoopSink] Add preheader to alias set
This patch fixes PR39695.
The original LoopSink only considers memory alias in loop body. But PR39695 shows that instructions following sink candidate in preheader should also be checked. This is a conservative patch, it simply adds whole preheader block to alias set. It may lose some optimization opportunity, but I think that is very rare because: 1 in the most common case st/ld to the same address, the load should already be optimized away. 2 usually preheader is not very large.
