The NB comments for filesystem changed permissions and added
a new enum `perm_options` which control how the permissions
are applied.

This implements than NB resolution

As I move towards implementing std::filesystem, there is a need to
make the existing tests run against both the std and experimental versions.
Additionally, it's helpful to allow running the tests against other
implementations of filesystem.

This patch converts the test to easily target either. First, it
adds a filesystem_include.hpp header which is soley responsible
for selecting and including the correct implementation. Second,
it converts existing tests to use this header instead of including
filesystem directly.

[X86] Merge the SSE and AVX versions of fp divs and sqrts in the SandyBridge/Haswell/Broadwell/Skylake scheduler models.

[X86] Give vpmsadbw the same itinerary as the SSE version so they'll be able to share the same generated scheduler class.

This matches Agner's data and is consistent with what the EVEX instructions were doing on SKX.

Strictly in a conversion operator's type, a <template-param> refers to a
<template-arg> that is further ahead in the mangled name. Instead of
doing a second parse to resolve these, introduce a
ForwardTemplateReference Node and back-patch the referenced
<template-arg> when we're in the right context.

This is also a correctness fix, previously we would only do a second
parse if the <template-param> was out of bounds in the current set of
<template-args>. This lead to misdemangles (gasp!) when the conversion
operator was a member of a templated struct, for instance.

llvm-svn: 328464

Rather than eagerly propagating up parameter pack sizes in Node ctors,
find the parameter pack size during printing. This is being done to
support back-patching forward referencing <template-param>s.

Fixes PR33569.

This continues the FP constant pattern matching improvements from:
https://reviews.llvm.org/rL327627
https://reviews.llvm.org/rL327339
https://reviews.llvm.org/rL327307

Several integer constant matchers also have this ability. I'm
separating matching of integer/pointer null from FP positive zero
and renaming/commenting to make the functionality clearer.

This patch throws a fatal error if an instregex entry doesn't actually match any instructions. This is part of the work to reduce the compile time impact of increased instregex usage (PR35955), although the x86 models seem to be relatively clean.

All the cases I encountered have now been fixed in trunk and this will ensure they don't get reintroduced.

[X86] Add the ability to override memory folding latency to schedules and add 1uop for memory folds for Intel models

The Intel models need an extra 1uop for memory folded instructions, plus a lot of instructions take a non-default memory latency which should allow us to use the multiclass a lot more to tidy things up.
