This patch uses the DroppedVariableStats class to add dropped variable

[IR] Don't include Module.h in Analysis.h (NFC) (#97023)

Replace it with a forward declaration instead. Analysis.h is pulled in
by all passes, but not all passes need to access the module.

This ensures !isSSA checks in the function work if the input MIR
happened to appear as SSA.

[MachineFunctionPass] Support -filter-passes for -print-changed

[MachineFunctionPass] Support -filter-passes for -print-changed

-filter-passes specifies a `PassID` (a lower-case dashed-separated pass name,
also used by -print-after, -stop-after, etc) instead of a CamelCasePass.

`-filter-passes=CamelCaseNewPMPass` seems like a workaround for new PM passes before
we can use lower-case dashed-separated pass names (as used by `-passes=`).

Example:
```
# getPassName() is "IRTranslator". PassID is "irtranslator"
llc -mtriple=aarch64 -print-changed -filter-passes=irtranslator < print-changed-machine.ll
```

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.

Add size remarks to MachineFunctionPass

This adds per-function size remarks to codegen, similar to what we have in the
IR layer as of r341588. This only impacts MachineFunctionPasses.

This does the same thing, but for `MachineInstr`s instead of just
`Instructions`. After this, when a `MachineFunctionPass` modifies the number of
`MachineInstr`s in the function it ran on, you'll get a remark.

To enable this, use the size-info analysis remark as before.

CodeGen: Remove pipeline dependencies on StackProtector; NFC

This re-applies r336929 with a fix to accomodate for the Mips target
scheduling multiple SelectionDAG instances into the pass pipeline.

PrologEpilogInserter and StackColoring depend on the StackProtector analysis
being alive from the point it is run until PEI, which requires that they are all
scheduled in the same FunctionPassManager. Inserting a (machine) ModulePass
between StackProtector and PEI results in these passes being in separate
FunctionPassManagers and the StackProtector is not available for PEI.

PEI and StackColoring don't use much information from the StackProtector pass,
so transfering the required information to MachineFrameInfo is cleaner than
keeping the StackProtector pass around. This commit moves the SSP layout
information to MFI instead of keeping it in the pass.
