When cross compiling lldb-server, do not create a host build
for building lldb-tblgeb when LLDB_TABLEGEN_EXE is already
provided. This avoids an expensive and time-consuming build step
if lldb-tblgen was already built previously for host.

The approach for handling reductions in the outer most
dimension follows that for inner most dimensions, outlined
below
First, transpose to move reduction dims, if needed
Convert reduction from n-d to 2-d canonical form
Then, for outer reductions, we emit the appropriate op
(add/mul/min/max/or/and/xor) and combine the results.

AttributeList::hasAttribute() is confusing, use clearer methods like
hasParamAttr()/hasRetAttr().
Add hasRetAttr() since it was missing from AttributeList.
Avoid doing the detection work inside the constructor. In addition to
polymorphism being unintuitive in constructors and other design problems
such as if an exception is thrown, the ScopDetection class is usable
without detection in the sense of "no Scop found" or "function skipped".
It is possible to generate the llvm.fmuladd.ppcf128 intrinsic, and there is no actual
FMA instruction that corresponds to this intrinsic call for ppcf128. Thus, this
intrinsic needs to remain as a call as it cannot be lowered to any instruction, which
also means we need to disable CTR loop generation for fma involving the ppcf128 type.
This patch accomplishes this behaviour.

This covers the SSE and AVX/AVX2 headers. AVX512 has a lot more macros
due to rounding mode.

Summary:
The assertion that both functions were not missing was incorrect and would
fail when one of the functions was missing. Fixed it and moved the
assertion earlier to check the input parameters to better capture
first-failure. Added lit test.

Since then, the SCEV pointer handling as been improved,

relanding the assertion from commit 141e845da5.
This patch implements the following check for TEAMS construct:
```
OpenMP Version 5.0 Teams construct restriction: A teams region can
only be strictly nested within the implicit parallel region or a target
region. If a teams construct is nested within a target construct, that
target construct must contain no statements, declarations or directives
outside of the teams construct.
```
Also add one test case for the check.

We use kShadowCnt (number of shadow cells per application granule)
when computing shadow, but it's wrong. We need the ratio
between shadow and app memory (how much shadow is larger than app memory),
which is kShadowMultiplier.
Currently both are equal to 4, so it works fine.
Use the correct constant.

This patch implements the following semantic checks for cancellation constructs:
```
OpenMP Version 5.0 Section 2.18.1: CANCEL construct restriction:
If construct-type-clause is taskgroup, the cancel construct must be
closely nested inside a task or a taskloop construct and the cancel
region must be closely nested inside a taskgroup region. If
construct-type-clause is sections, the cancel construct must be closely
nested inside a sections or section construct. Otherwise, the cancel
construct must be closely nested inside an OpenMP construct that matches
the type specified in construct-type-clause of the cancel construct.
OpenMP Version 5.0 Section 2.18.2: CANCELLATION POINT restriction:
A cancellation point construct for which construct-type-clause is
taskgroup must be closely nested inside a task or taskloop construct,
and the cancellation point region must be closely nested inside a
taskgroup region. A cancellation point construct for which
construct-type-clause is sections must be closely nested inside a
sections or section construct. A cancellation point construct for which
construct-type-clause is neither sections nor taskgroup must be closely
nested inside an OpenMP construct that matches the type specified in
construct-type-clause.
```
Also add test cases for the check.
