[flang][flang-omp-report] Add flang-omp-report summarising script
The flang plugin ``flang-omp-report`` takes one fortran file in and returns a
YAML report file of the input file. This becomes an issue when you want to
analyse an entire project into one final report.
The purpose of this Python script is to generate a final YAML
report from all of the files generated by ``flang-omp-report``. The report can
have (currently) 2 formats; summary and log. Summary focuses on "summarizing"
all constructs and there clauses from all YAML files with a corresponding "count"
for each. Log instead combines the generated YAML files into one report in a
"cleaner" format. (Pseudo) Examples can be found for both formats at the top of
the script.

Make enum iteration with seq safe by default
By default `llvm::seq` would happily iterate over enums, which may be unsafe if the enum values are not continuous. This patch disable enum iteration with `llvm::seq` and `llvm::seq_inclusive` and adds two new functions: `enum_seq` and `enum_seq_inclusive`.
To make sure enum iteration is safe, we require users to declare their enum types as iterable by specializing `enum_iteration_traits<SomeEnum>`. Because it's not always possible to add these traits next to enum definition (e.g., for enums defined in external libraries), we provide an escape hatch to allow iteration on per-callsite basis by passing `force_iteration_on_noniterable_enum`.
The main benefit of this approach is that these global declarations via traits can appear just next to enum definitions, making easy to spot when enums are miss-labeled, e.g., after introducing new enum values, whereas `force_iteration_on_noniterable_enum` should stand out and be easy to grep for.
This emerged from a discussion with gchatelet@ about reusing llvm's `Sequence.h` in lieu of https://github.com/GPUOpen-Drivers/llpc/blob/dev/lgc/interface/lgc/EnumIterator.h.

[clang][objc] Speed up populating the global method pool from modules.
For each selector encountered in the source code, we need to load
selectors from the imported modules and check that we are calling a
selector with compatible types.
At the moment, for each module we are storing methods declared in the
headers belonging to this module and methods from the transitive closure
of imported modules. When a module is imported by a few other modules,
methods from the shared module are duplicated in each importer. As the
result, we can end up with lots of identical methods that we try to add
to the global method pool. Doing this duplicate work is useless and
relatively expensive.
Avoid processing duplicate methods by storing in each module only its
own methods and not storing methods from dependencies. Collect methods
from dependencies by walking the graph of module dependencies.
The issue was discovered and reported by Richard Howell. He has done the
hard work for this fix as he has investigated and provided a detailed
explanation of the performance problem.

X86InstrInfo: Support immediates that are +1/-1 different in optimizeCompareInstr
This is a re-commit of
e2c7ee0743592e39274e28dbe0d0c213ba342317 which
was reverted in
a2a58d91e82db38fbdf88cc317dcb3753d79d492. This includes
a fix to consistently check for EFLAGS being live-out. See phabricator
review.
Original Summary:
This extends `optimizeCompareInstr` to re-use previous comparison
results if the previous comparison was with an immediate that was 1
bigger or smaller. Example:
CMP x, 13
...
CMP x, 12 ; can be removed if we change the SETg
SETg ... ; x > 12 changed to `SETge` (x >= 13) removing CMP
Motivation: This often happens because SelectionDAG canonicalization
tends to add/subtract 1 often when optimizing for fallthrough blocks.
Example for `x > C` the fallthrough optimization switches true/false
blocks with `!(x > C)` --> `x <= C` and canonicalization turns this into
`x < C + 1`.

[indvars] Rotate zext though icmp to reduce loop varying computation
This change looks for cases where we can prove that an exit test of a loop can be performed in a narrower bitwidth, and that by doing so we can replace a loop-varying extend with a loop-invariant truncate.
The motivation here is that doing this unblocks the trip count analysis for narrow IVs involved in extended compare exit tests. It also has the nice side effect of simply making the code faster, even if we gain no other benefit from the improved analysis ability.
I've noted a few places this could be extended, but I think this stands reasonable on it's own as well.
