[LSR] Improve filtered uses in NarrowSearchSpaceByPickingWinnerRegs
NarrowSearchSpaceByPickingWinnerRegs has an aggressive filtering method to
reduce the complexity of the search space down by picking a best formula with
the highest number of reuses and assuming it will yield profitable reuse. In
certain cases we can find a best formula like {X+30,+,1} and later check a
formula like {X,+,1} with the same number of Uses. On some architectures it
can be better to pick {X,+,1}, especially if an offset of 30 can be used as a
legal addressing mode, but -30 cannot. That happens under Thumb1 code, which
has fairly limited addressing modes. This patch adds a check to see if it can
pick the simpler formula, if it looks more profitable.

[LowerTypeTests] Support generating Armv6-M jump tables.
The LowerTypeTests pass emits a jump table in the form of an
`inlineasm` IR node containing a string representation of some
assembly. It tests the target triple to see what architecture it
should be generating assembly for. But that's not good enough for
`Triple::thumb`, because the 32-bit PC-relative `b.w` branch
instruction isn't available in all supported architecture versions. In
particular, Armv6-M doesn't support that instruction (although the
similar Armv8-M Baseline does).
Most of this patch is concerned with working out whether the
compilation target is Armv6-M or not, which I'm doing by going through
all the functions in the module, retrieving a TargetTransformInfo for
each one, and querying it via a new method I've added to check its
SubtargetInfo. If any function's TTI indicates that it's targeting an
architecture supporting B.W, then we assume we're also allowed to use
B.W in the jump table.
The Armv6-M compatible jump table format requires a temporary
register, and therefore also has to use the stack in order to restore
that register.
Another consequence of this change is that jump tables on Arm/Thumb
are no longer always the same size. In particular, on an architecture
that supports Arm and Thumb-1 but not Thumb-2, the Arm and Thumb
tables are different sizes from //each other//. As a consequence,
``getJumpTableEntrySize`` can no longer base its answer on the target
triple's architecture: it has to take into account the decision that
``selectJumpTableArmEncoding`` made, which meant I had to move that
function to an earlier point in the code and store its answer in the
``LowerTypeTestsModule`` class.

- introduces a framework to lower array constructor according to
different strategies: A common analysis of the array constructor is
done, and based on that, a lowering startegy is selected and driven
through the ac-values of the array constructor. See
ConvertArrayConstructor.cpp comments for more details.
- implements the first strategy that creates a temporary inlined and
updates it with inlined code. This strategy can only be used if the
temporary can be pre-allocated (i.e: the extents and length parameters
can be pre-computed without evaluating any ac-values), and if all the
ac-value expressions are scalars.
For the sake of simplicity, characters and derived type will be enabled

[lldb] Remove pydoc import during script interpreter init
The Python script interpreter imports `pydoc` during initialization, but this can be
slow in some cases, and doesn't seem to be necessary any more.
This can be slow because pydoc may execute shell commands (for example `xcrun` on
macOS). The shell commands may have variable performance, depending on their caches and
search space.
The 2012 bug report for the original commit (
f71a8399997bfdc1ddeeb30c6a8897554a11c382)
says the following:
> "script help" in lldb pipes the help documentation through less(1) but there's some
> problem with the key handling and often the keys you'd use to move in less (space to
> move down a page, 'q' to quit) are not received by less (they're going to lldb
> instead)
This was resolved at the time by overriding `pydoc`'s pager to be the `plainpager`
function.
I have manually tested `script help(lldb.SBDebugger)` and found no issues with the
pager, including using "space" for paging, "/" for searching, and "q" for quitting.
The presumption is that lldb and/or Python have improved I/O handling that eliminates
the original problem.
The original bug report gave an ~/.lldbinit workaround:
```
script import pydoc; pydoc.pager = pydoc.plainpager
```
Note that calling Python's `help()` will import `pydoc`, but this will only happen for
users who use `help()` from the `script` command.

[X86][Win64] Avoid statepoints prior to SEH epilogue
This patchs purpose is very similar to https://reviews.llvm.org/D119644
The gist of the issue is that SEH unwinding has certain invariants around call instructions. One of those is that a call instruction must not be immediately followed by the function epilogue. Failing to do so leads to Windows' unwinder not recognizing the frame and skipping it when unwinding the stack.
LLVM ensures this invariant by inserting a noop after a call prior to an epilogue. The implementation however, makes the unfortunate assumption that pseudo instructions may not be calls, leading to statepoints being skipped and no noop being inserted.
This patch fixes that issue by only skipping over pseudo instructions that aren't calls.
