Thomas Lively 88962cea46 [WebAssembly] Restore builtins and intrinsics for pmin/pmax
Partially reverts 85157c0079, which had removed these builtins and intrinsics
in favor of normal codegen patterns. It turns out that it is possible for the
patterns to be split over multiple basic blocks, however, which means that DAG
ISel is not able to select them to the pmin/pmax instructions. To make sure the
SIMD intrinsics generate the correct instructions in these cases, reintroduce
the clang builtins and corresponding LLVM intrinsics, but also keep the normal
pattern matching as well.

Thomas Lively 2456e11614 [WebAssembly] Add SIMD intrinsics using unsigned integers
For each SIMD intrinsic function that takes or returns a scalar signed integer
value, ensure there is a corresponding intrinsic that returns or an
unsigned value. This is a convenience for users who use -Wsign-conversion so
they don't have to insert explicit casts, especially when the intrinsic
arguments are integer literals that fit into the unsigned integer type but not
the signed type.

Jon Chesterfield 2a47a84b40 [openmp][nfc] Refactor GridValues
Remove redundant fields and replace pointer with virtual function

Of fourteen fields, three are dead and four can be computed from the
remainder. This leaves a couple of currently dead fields in place as
they are expected to be used from the deviceRTL shortly. Two of the
fields that can be computed are only used from codegen and require a
log2() implementation so are inlined into codegen instead.

This change leaves the new methods in the same location in the struct
as the previous fields for convenience at review.

Corentin Jabot bdeda959ab Make wide multi-character character literals ill-formed
This implements P2362, which has not yet been approved by the
C++ committee, but because wide-multi character literals are
implementation defined, clang might not have to wait for WG21.

This change is also being applied in C mode as the behavior is
implementation-defined in C as well and there's no benefit to
having different rules between the languages.

The other part of P2362, making non-representable character
literals ill-formed, is already implemented by clang

Aaron Ballman 48f73ee666 Fix assertion when generating diagnostic for inline namespaces
When calculating the name to display for inline namespaces, we have
custom logic to try to hide redundant inline namespaces from the
diagnostic. Calculating these redundancies requires performing a lookup
in the parent declaration context, but that lookup should not try to
look through transparent declaration contexts, like linkage
specifications. Instead, loop up the declaration context chain until we
find a non-transparent context and use that instead.

This fixes PR49954.

Jennifer Yu c274b19866 Add implicit map for a list item appears in a reduction clause.
A new rule is added in 5.0:
If a list item appears in a reduction, lastprivate or linear clause
on a combined target construct then it is treated as if it also appears
in a map clause with a map-type of tofrom.

Currently map clauses for all capture variables are added implicitly.
But missing for list item of expression for array elements or array
sections.

The change is to add implicit map clause for array of elements used in
reduction clause. Skip adding map clause if the expression is not
mappable.
Noted: For linear and lastprivate, since only variable name is
accepted, the map has been added though capture variables.

To do so:
During the mappable checking, if error, ignore diagnose and skip
adding implicit map clause.

The changes:
1> Add code to generate implicit map in ActOnOpenMPExecutableDirective,
   for omp 5.0 and up.
2> Add extra default parameter NoDiagnose in ActOnOpenMPMapClause:
Use that to skip error as well as skip adding implicit map during the
mappable checking.

Note: there are only tow places need to be check for NoDiagnose. Rest
of them either the check is for < omp 5.0 or the error already generated for
reduction clause.

Motivation is to later safely remove dead fields and replace redundant ones

duplication than the arrays of integers require.

Bjorn Pettersson 36d5138619 [NewPM] Make some sanitizer passes parameterized in the PassRegistry
Refactored implementation of AddressSanitizerPass and
HWAddressSanitizerPass to use pass options similar to passes like
MemorySanitizerPass. This makes sure that there is a single mapping
from class name to pass name (needed by D108298), and options like
-debug-only and -print-after makes a bit more sense when (despite
that it is the unparameterized pass name that should be used in those
options).

A result of the above is that some pass names are removed in favor
of the parameterized versions:
- "khwasan" is now "hwasan<kernel;recover>"
- "kasan" is now "asan<kernel>"
- "kmsan" is now "msan<kernel>"

Jon Chesterfield dbd7bad9ad [openmp] Annotate tmp variables with omp_thread_mem_alloc
Fixes miscompile of calls into ocml. Bug 51445.

The stack variable `double __tmp` is moved to dynamically allocated shared
memory by CGOpenMPRuntimeGPU. This is usually fine, but when the variable
is passed to a function that is explicitly annotated address_space(5) then
allocating the variable off-stack leads to a miscompile in the back end,
which cannot decide to move the variable back to the stack from shared.

This could be fixed by removing the AS(5) annotation from the math library
or by explicitly marking the variables as thread_mem_alloc. The cast to
AS(5) is still a no-op once IR is reached.
