As correctly pointed out by Martin on the mailing list, Python should
only be auto-enabled if SWIG is found as well. This moves the logic of
finding SWIG into FindPythonInterpAndLibs to make that possible.

To make diagnosing easier I've included a status message to convey why
Python support is disabled.

In TestConvenienceVariables I changed %t from a file to a directory.
This tripped up mkdir which can't deal with an existing file at the
given location. In order to solve this issue on the bots I added an
`rm -rf %t` statement, but now the Windows bot complains that "This
function is not supported on this system".

If you never ran the test suite wit this temporary workaround, the test
might fail. If this happens please remove what %t expands to in the lit
output and rerun the test.

Summary:
This is analogous to D58943, which correctly finds the corresponding
fixup. However, when linker relaxations are disabled and we evaluate the
fixup, we need to also ensure we use an offset of 0 rather than the size
of the previous fragment.

additional platforms than just darwin.

This was returning a pointer to a stack-allocated memory location. This
works for Python where we return a PythonString which must own the
underlying string.

Factor out common logic into some reasonable commented helper functions. In the process, ensure that the in-block vs cross-block cases are handled the same. They previously weren't.

According to D53384, the default was switched from -fno-PIC to -fPIC to
work around a -fsanitize=leak bug on big-endian.

This gratuitous difference between little-endian and big-endian is
undesired, and not acceptable on powerpc64-unknown-freebsd.  If
-fsanitize=leak still has the problem, we should consider defaulting to
-fPIC/-fPIE only when -fsanitize=leak is specified (see SanitizerArgs::requiresPIE())

powerpc64-ibm-aix is unaffected: it still defaults to -fPIC.
powerpc64-linux-musl is unaffected (-fPIE since D39588): it still defaults to -fPIE.

[X86] Add SSE4.1 command lines to vec-strict-inttofp-128.ll to cover the v2i64->v2f32 strict_uitofp codegen. NFC

This reverts commit 52366088.

I accidentally pushed this before supporting changes.

Extend the SBTarget class with a string conversion operator and reuse
the same code between Python and Lua. This should happen for all the SB
classes, but I'm doing just this one as an example and for use in a test
case.

Summary:
Remove the restrictions that preventing "asm goto" from returning non-void
values. The values returned by "asm goto" are only valid on the "fallthrough"
path.

4e85ca95 missed updating the legal
condition type set for pointers with any unrecognized address space.

This was only applying the deeper nested zext pattern, and missing the
special case code size fold.

[clang-tidy] modernize-use-using uses AST and now supports struct defintions and multiple types in a typedef

Summary:
It now handles `typedef`s that include comma-separated multiple types, and handles embedded struct definitions, which previously could not be automatically converted.

For example, with this patch `modernize-use-using` now can convert:

typedef struct { int a; } R_t, *R_p;

to:

using R_t = struct { int a; };
using R_p = R_t*;

`-ast-dump` showed that the `CXXRecordDecl` definitions and multiple `TypedefDecl`s come consecutively in the tree, so `check()` stores information between calls to determine when it is receiving a second or additional `TypedefDecl` within a single `typedef`, or when the current `TypedefDecl` refers to an embedded `CXXRecordDecl` like a `struct`.

On a dirty build directory the new mkdir fails because the file already
exists and is not a directory.

This test was passing even when the output of lldb.target was empty.
I've made the test more strict by checking explicitly for the target
name and by using CHECK-NEXT lines.

This reverts commit 640d0ba8.

Configure CMake to setup source-groups for Polly. Source groups
describe how source files should be organized in IDEs. By default, all
headers are dumped into one folder under PollyCore and all source files
into another. On disk, these files are organized into folders, but this
isn't reflected in the IDE. This change uses CMake source groups to have
the IDE reflect the on disk layout. This will make it easier to visualize
the project structure for users of Visual Studio and XCode
