[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.

LoopNest Analysis expansion to return instructions that prevent a Loop
Nest from being perfect
Expand LoopNestAnalysis to return the full list of instructions that
cause a loop nest to be imperfect.
LoopNest Analysis expansion to return instructions that prevent a Loop
Nest from being perfect
Expand LoopNestAnalysis to return the full list of instructions that
cause a loop nest to be imperfect. This is useful for other passes to
know if they should continue for in the inner loops.
Added New function getInterveningInstructions
that returns a small vector with the instructions that prevent a loop
for being perfect. Also added a couple of helper functions to reduce
code duplication.

[LoopNest]: Analysis to discover properties of a loop nest.
Summary: This patch adds an analysis pass to collect loop nests and
summarize properties of the nest (e.g the nest depth, whether the nest
is perfect, what's the innermost loop, etc...).
The motivation for this patch was discussed at the latest meeting of the
LLVM loop group (https://ibm.box.com/v/llvm-loop-nest-analysis) where we
discussed
the unimodular loop transformation framework ( “A Loop Transformation
Theory and an Algorithm to Maximize Parallelism”, Michael E. Wolf and
Monica S. Lam, IEEE TPDS, October 1991). The unimodular framework
provides a convenient way to unify legality checking and code generation
for several loop nest transformations (e.g. loop reversal, loop
interchange, loop skewing) and their compositions. Given that the
unimodular framework is applicable to perfect loop nests this is one
property of interest we expose in this analysis. Several other utility
functions are also provided. In the future other properties of interest
can be added in a centralized place.
