The flag "--no-as-needed" is not recognized by the linker on macOS making the following tests fail:
ompt/loadtool/tool_available/tool_available.c
ompt/loadtool/tool_not_available/tool_not_available.c
This patch removes this flag for macOS and adds it only for Linux and Windows.
I tested it on Ubuntu 16.04 and macOS HighSierra, with Clang/LLVM 6.0.1 and OpenMP trunk.
This solution was also discussed in the OpenMP-dev mailing list.

This patch also adds instructions for predicated FP square-root and
reciprocal exponent.
The added instructions are:
- FRINTI Round to integral value (current FPCR rounding mode)
- FRINTX Round to integral value (current FPCR rounding mode, signalling inexact)
- FRINTA Round to integral value (to nearest, with ties away from zero)
- FRINTN Round to integral value (to nearest, with ties to even)
- FRINTZ Round to integral value (toward zero)
- FRINTM Round to integral value (toward minus Infinity)
- FRINTP Round to integral value (toward plus Infinity)
- FSQRT Floating-point square root
- FRECPX Floating-point reciprocal exponent

Non-homogenous aggregates are passed in consecutive GPRs, in GPRs and in memory,
or in memory. This patch ensures that float128 members of non-homogenous
aggregates are passed via VSX registers.
This is done via custom lowering a bitcast of a build_pari(i64,i64) to float128
to a new PPCISD node, BUILD_FP128.

We have patterns for SELECTS that top at v1i1 and we have a pattern for (v1i1 (scalar_to_vector GR8)). The patterns being removed here do the same thing as the two other patterns combined so there is no need for them.

Previously we could only negate the FMADD opcodes. This used to be mostly ok when we lowered FMA intrinsics during lowering. But with the move to llvm.fma from target specific intrinsics, we can combine (fneg (fma)) to (fmsub) earlier. So if we start with (fneg (fma (fneg))) we would get stuck at (fmsub (fneg)).
This patch fixes that so we can also combine things like (fmsub (fneg)).

There's a regression in here due to inability to combine fneg inputs of X86ISD::FMSUB/FNMSUB/FNMADD nodes.

We have bailout hacks based on min/max in various places in instcombine
that shouldn't be necessary. The affected test was added for:
D48930
...which is a consequence of the improvement in:
D48584 (https://reviews.llvm.org/rL336172)
I'm assuming the visitTrunc bailout in this patch was added specifically
to avoid a change from SimplifyDemandedBits, so I'm just moving that
below the EvaluateInDifferentType optimization. A narrow min/max is still
a min/max.

Summary: As per `Agner's Microarchitecture doc
(21.8 AMD Bobcat and Jaguar pipeline - Dependency-breaking instructions)`,
these, like zero-idioms, are dependency-breaking,

It appears that llvm uses unbuffered C++ streams. So, we should not

Summary:
This change fixes one issue with `lldb.command`, and also reduces the implementation.
The fix: a command function's docstring was not shown when running `help <command_name>`. This is because the docstring attached the source function is not propagated to the decorated function (`f.__call__`). By returning the original function, the docstring will be properly displayed by `help`.
Also with this change, the command name is assumed to be the function's name, but can still be explicitly defined as previously.
Additionally, the implementation was updated to:
* Remove inner class
* Remove use of `inspect` module
* Remove `*args` and `**kwargs`

Apparently there's a difference between using LLVM_RUNTIME_OUTPUT_INTDIR
and LLVM_BINARY_DIR. The former will point to the current binary
directory (i.e. that where lldb is built) while the former will always
point to LLVM's. This was causing trouble for the swift build but should
be a transparent for upstream lldb.
