Remove "cl::value_desc("jcc, fused, jmp, call, ret, indirect"),", which
makes the option+it's cl::value_desc too long in all of help.

The change in 9b84dabc uses a newer
syntax which not all the builders support.  Use an explicit `OR` over
the languages instead to repair the builders.

Summary: Adds an option called `AddConstToQualified` to readability-qualified-auto to toggle adding const to the auto typed pointers and references. By default its enabled but in the LLVM module its disabled.

[X86] Use MVT::f80 for the result type of the FLD used to convert from SSE register to X87 register in FP_TO_INTHelper.

This patch limits adding -UNDEBUG to C and C++ files so that projects
can include files compiled with compilers that don't recognize this
argument (Swift e.g.).

add_definitions does not expand generators, hence the change from
add_definitions to add_compile_options.

Patch by Evan Wilde!

This reverts commit 1d58a7c8.

We don't need tests for truncating the result. There's nothing
special about those truncates.

We can test llrint/llround for 64-bit and 32-bit targets in the same file.
Same with lrint/lround with i32 result result. lrint/lround with
64-bit result should only occur on a 64-bit target.

Add some missing tests for f80 conversions.

Fix attempt

this is part of the implementation of http://lists.llvm.org/pipermail/llvm-dev/2019-December/137632.html

this patch gives the basis of building an assume to preserve all information from an instruction and add support for building an assume that preserve the information from a call.

[test] More tests to target specific directories after CodeGenPrepare requires TargetPassConfig (D73754)

Follow-up for D73754

DL is assigned in CodeGenPrepare::runOnFunction and is guaranteed to be
non-null.

casued buildbot failure

This reverts commit 8ebe0015.

The code paths in the absence of TargetMachine, TargetLowering or
TargetRegisterInfo are poorly tested. As rL285987 said, requiring
TargetPassConfig allows us to delete many (untested) checks littered
everywhere.

We want to allow splat value transforms to improve PR44588 and related bugs:
https://bugs.llvm.org/show_bug.cgi?id=44588
...but to do that, we need to know if values are splatted from the same,
specific index (lane) rather than splatted from an arbitrary index.

We can improve the undef handling with 1-liner follow-ups because the
Constant API optionally allow undefs now.

Summary:
this patch makes tablegen generate llvm attributes in a more generic and simpler (at least to me).

changes:  make tablegen generate
...
ATTRIBUTE_ENUM(Alignment,align)
ATTRIBUTE_ENUM(AllocSize,allocsize)
...
which can be used to generate most of what was previously used and more.

Tablegen was also generating attributes from 2 identical files leading to identical output. so I removed one of them and made user use the other.

This reverts commit e34801c8 and the followup due to multiple
problems.

I've tried to keep the tests and RDA parts where possible, as those
still seem useful.

The two functions are identical.
