This ports and improves on some existing llvm-readobj -codeview dumping
functionality that llvm-pdbutil lacked.

Helpful for comparing inline line tables between MSVC and clang.

clang was encoding pointers to typedefs as if they were pointers to
structs because that is apparently what gcc is doing.

For example:

```
@class Class1;

typedef NSArray<Class1 *> MyArray;

void foo1(void) {
  const char *s0 = @encode(MyArray *); // "^{NSArray=#}"
  const char *s1 = @encode(NSArray<Class1 *> *); // "@"
}
```

This commit removes the code that was there to make clang compatible
with gcc and make clang emit the correct encoding for ObjC pointers,
which is "@".

On mouse-hover event it pops up on variables. Similar to note pieces it
supports `plist` diagnostics as well.

It is optional, on by default: `add-pop-up-notes=true`.

Extra: In HTML reports `background-color: LemonChiffon` was too light,
changed to `PaleGoldenRod`.

Since byval is now a typed attribute it gets sorted slightly differently by
LLVM when the order of attributes is being canonicalized. This updates the few
Clang tests that depend on the old order.

llvm-svn: 362013

When we switch to opaque pointer types we will need some way to describe
how many bytes a 'byval' parameter should occupy on the stack. This adds
a (for now) optional extra type parameter.

If present, the type must match the pointee type of the argument.

Note to front-end maintainers: if this causes test failures, it's probably
because the "byval" attribute is printed after attributes without any parameter
after this change.

llvm-svn: 362012

Summary: Some environment create less statements so make them generic.
llvm-svn: 362011

In particular, don't call get_target_flags_for_arch() since that
will cause an error in some situations:

If DARWIN_iossim_ARCHS=i386;x86_64, DARWIN_osx_ARCHS=x86_64, and
DARWIN_iossym_SYSROOT isn't set (due to the simulator sysroot not being
available), then config-ix.cmake won't add i386 to COMPILER_RT_SUPPORTED_ARCH
but ubsan's test/CMakeLists.txt would call get_target_flags_for_arch()
with i386, which would then run into the error in
get_target_flags_for_arch().

Having these conditions isn't ideal. The background here is that we
configure our mac-hosted trunk bots all the same (so they all have the
same DARWIN_*_archs, and we don't easily know if a mac host bot is
targeting mac or ios at the place where we call cmake), but only the
ios-targeting bots have ios sysroots available.

This will hopefully unbreak that use case without impacting anything
else -- and it makes ubsan and asan test setup more alike.

llvm-svn: 362010

Don't bother coming up with a -cc1 run-line ourselves.

This, in particular, gets rid of a macOS-specific code path.

Summary:
The runtimes use `*_STANDALONE_BUILD=OFF` to signify that clang is an in-tree target. This is not the case with the runtime builds, so we really need this set to `ON`.

In order to resolve the issues phosek was having with checks, we should use checks that don't link. We can use compiler-rt's `try_compile_only` as a basis for that.

This patch is *required* to be able to run the runtime libraries check-* targets.

Currently there's not really a good way to iterate over the language runtimes a
process has. This is sometimes desirable (as seen in my change to Thread).
Additionally, there's not really a good reason to iterate over every available
language, but rather only over languages for which we have a plugin loaded.
