Consider this piece of Fortran (from the test blockconstruct02.f90):

[clang] Add __is_target_variant_{os,environment} builtins
Xcode 13's clang has them. For the included testcase, Xcode's clang
behaves like the implementation in this patch.
Availability.h in the macOS 12.0 SDK (part of Xcode 13, and the current
stable version of the macOS SDK) does something like:
#if defined(__has_builtin)
...
#if __has_builtin(__is_target_os)
#if __has_builtin(__is_target_environment)
#if __has_builtin(__is_target_variant_os)
#if __has_builtin(__is_target_variant_environment)
#if (... && ((__is_target_os(ios) && __is_target_environment(macabi)) || (__is_target_variant_os(ios) && __is_target_variant_environment(macabi))))
#define __OSX_AVAILABLE_STARTING(_osx, _ios) ...
#define __OSX_AVAILABLE_BUT_DEPRECATED(_osxIntro, _osxDep, _iosIntro, _iosDep) ...
#define __OSX_AVAILABLE_BUT_DEPRECATED_MSG(_osxIntro, _osxDep, _iosIntro, _iosDep, _msg) ...
So if __has_builtin(__is_target_variant_os) or
__has_builtin(__is_target_variant_environment) are false, these defines are not
defined.
Most of the time, this doesn't matter. But open-source clang currently fails
to commpile a file containing only `#include <Security/cssmtype.h>` when
building for catalyst by adding a `-target arm64-apple-ios13.1-macabi` triple,
due to those __OSX_AVAILABLE macros not being set correctly.
If a potential future SDK version were to include cssmtype.h transitively
from a common header such as `<Foundation/Foundation.h>`, then it would become
close to impossible to build Catalyst binaries with open-source clang.
To fix this for normal catalyst builds, it's only necessary that
__has_builtin() evaluates to true for these two built-ins -- the implementation
of them doesn't matter. But as a courtesy, a correct (at least on the test
cases I tried) implementation is provided. (This should also help people who
try to build zippered code, where having the correct implementation does
matter.)

[RISCV] Enable fixed length vectors and loop vectorization with same
This change enables the use of RISCV's variable length vector registers for fixed length vectors in the IR, and implicitly enables various IR transforms which generate fixed length vectors if legal (e.g. LoopVectorize). Specifically, this enables fixed length vectors which are known to be inbounds of the underlying variable hardware size.
For context, remember that the +V extension provides a minimum VLEN of 128. The embedded variants provide lower minimums. The analogy here is essentially vectorizing for SSE on a machine which may or may not include AVX2/AVX512. We won't get full utilization by default, but we will get some benefit. And of course, with an explicit mcpu we can vectorize to the exact target hardware.
The LV impact is mostly related to vectorizer robustness. In cases we haven't yet fully implemented scalable vectorization support, we can fall back to fixed length vectorization.
SLP has been disabled for now, even when fixed vectors are enabled. See a310637 and associated review. There are a few addiitional code quality issues which need worked through before turning SLP on would be reasonable.

This change implements a TTI query with the goal of disabling slp vectorization on RISCV. The current default configuration disables SLP already, but its current tied to the ability to lower fixed length vectors. Over in D131508, I want to enable fixed length vectors for purposes of LoopVectorizer, but preliminary analysis has revealed a couple of SLP specific issues we need to resolve before enabling it by default. This change exists to allow us to enable LV without SLP.
