check-clang (the target that runs all clang tests) used to
only depend on clang-check (a binary like clang-tidy,
clang-refactor, etc) if the static analyzer is enabled.
However, several lit tests call clang-check unconditionally,
so always depend on it.
Fixes a "could not find clang-check" lit warning in clean builds with
the static analyzer disabled.
Also sort the deps in the CMake file and put just one dep on each line.

Summary:
To be able to successfully build OpenMP on 32-bit FreeBSD, such as
FreeBSD/i386, I first had to provide a few wrappers (see D60916), and
then add `KMP_OS_FREEBSD` to the list of defines checked for 32-bit
architectures in `kmp_runtime.cpp`.
I have successfully built libomp.so and ran a bunch of test programs on
FreeBSD/i386 with this.

We correct some typos in `ActOnArraySubscriptExpr` and
`ActOnOMPArraySectionExpr`, so when their result is `ExprError`, we can
end up correcting delayed typos in the same expressions again. In
general it is OK but when `NumTypos` is incorrect, we can hit the
assertion
> Assertion failed: (Entry != DelayedTypos.end() && "Failed to get the state for a TypoExpr!"), function getTypoExprState, file clang/lib/Sema/SemaLookup.cpp, line 5219.
Fix by replacing some subscript `ExprResult` with typo-corrected expressions
instead of keeping the original expressions. Thus if original expressions
contained `TypoExpr`, we'll use corrected expressions instead of trying to
correct them again.

Implemented task modifier in two versions - one without taking into account
omp_orig variable (the omp_orig still can be processed by compiler without help
of the library, but each reduction object will need separate initializer with
global access to omp_orig), another with omp_orig variable included into
interface (single initializer can be used for multiple reduction objects of
the same type). Second version can be used when the omp_orig is not globally
accessible, or to optimize code in case of multiple reduction objects
of the same type.

This test checks whether crtbegin.o and crtend.o appear on the link
line, but names of these files may be affected by the choice of the
rtlib, specifically when compiler-rt is used as the default rtlib
the names will be clang_rt.crtbegin.o and clang_rt.crtend.o instead
of crtbeginS.o and crtendS.o. To avoid the test failure, explicitly
request to use the platform rtlib.

Summary:
* The getActionDefinitionsBuilder() is now documented.
* Includes descriptions of the various actions (legal*, widenScalar*, lower*,
etc).
* Includes descriptions of the various predicates (*If, *For,
*ForCartesianProduct, etc.)
* Includes the rule-order details
* Removed the out-of-date prohibition on non-power-of-2 types.
* Removed the Vector types section since it was incorrect and vectors follow the
same ruleset as scalars. They're only special in the sense that more of the
actions and predicates are meaningful for them (e.g. moreElements).
* Clarified the position on context sensitive legality (which is not permitted)
and contrasted this with context sensitive legalization (which is permitted).

customize for WASI libc specifically.

If the user passes a flag like `-version` to a program, it's more likely
they mean `--version` than `-version:`, since there's no parameter
passed. Hence, give delimited arguments a penalty of 1 if the user input
doesn't contain the delimiter or no data after it.
The motivation is that with this, lld-link can suggest "--version"
instead of "-version:" for "-version" and "-nodefaultlib" instead of
"-nodefaultlib:" for "-nodefaultlibs".

Commit
rL331949: SCEV] Do not use induction in isKnownPredicate for simplification umax
changed the codepath for umax from isKnownPredicate to
isKnownViaNonRecursiveReasoning to avoid compile time blow up (and as
I found out also stack overflows). However, there is an exact copy of
the code for umax that was lacking this change. In D50167 I want to unify
these codepaths, but to avoid that being a behavior change for the smax
case, pull this independent bit out of it.

Summary:
Various tests in the `lit` testing suite expect specific return codes
and forms of diagnostic message from utility programs. As per
POSIX.1-2017 XCU Section 1.4, Utility Description Defaults, "[the]
format of diagnostic messages for most utilities is unspecified".
The STDERR subsections of the `cat` and `wc` utilities merely indicate
that "[the] standard error shall be used only for diagnostic messages".
The corresponding EXIT STATUS subsections merely indicate, with regard
to errors, an exit value of >0.
The affected tests are updated to accept the applicable diagnostic
message as produced by the utilities on AIX. The exit value is
normalized using `not` as necessary.

Prior to this, OptTable::findNearest() thought that the input `--foo`
had an editing distance of 0 from an existing flag `--foo=`, which made
it suggest flags with delimiters more often than flags without one.
After this, it correctly assigns this case an editing distance of 1.

Summary:
This change was part of D46460. However, in the meantime rL341926 fixed the
correctness issue here. What remained was the performance issue in setLoopID
where it would iterate through all blocks in the loop and their successors,
rather than just the predecessor of the header (the later presumably being
much faster). We already have the `getLoopLatches` to compute precisely these
basic blocks in an efficient manner, so just use it (as the original commit
did for `getLoopID`).

In preparation for supporting ILP32 on AArch64, this modifies the SelectionDAG
builder code so that pointers are allowed to have a larger type when "live" in
the DAG compared to memory.
Pointers get zero-extended whenever they are loaded, and truncated prior to
stores. In addition, a few not quite so obvious locations need updating:
* A GEP that has not been marked inbounds needs to enforce the IR-documented
2s-complement wrapping at the memory pointer size. Inbounds GEPs are
undefined if they overflow the address space, so no additional operations
are needed.
* Signed comparisons would give incorrect results if performed on the
zero-extended values.
This shouldn't affect CodeGen for now, but will become active when the AArch64
ILP32 support is committed.

The fork-siguser.test and fork.test intermittently fail on the AArch64
buildbot. Unfortunately these failures are not reproducible on a similar
machine and seem to fail when the machines are under load. Before
suggesting the tests be marked unsupported for AArch64 we'd like to see
if we can get some more information about the failures to see if it helps
us reproduce. This patch adds --dump-input-on-failure to the FileCheck
commands to see if we can get some more information about the failures.
