Lang Hames ed2df18a48 [ORC] Move ORC Core symbol map and set types into their own header: CoreTypes.h.
This will allow other utilities (including a future RuntimeDyld replacement) to
use these types without pulling in the major Core types (JITDylib, etc.).

Roman Lebedev deb8089a71 [compiler-rt] UBSan: just completely disable two alignment-assumption tests for now.
And they are faling on clang-cmake-armv7-full too.
*ONLY* these two.
I'm not sure what to make of it.

Perhaps doing a malloc and checking that pointer will
make them fail as expected?

Zachary Turner 576495e67b [SymbolFile] Remove SymbolContext parameter from FindTypes.
This parameter was only ever used with the Module set, and
since a SymbolFile is tied to a module, the parameter turns
out to be entirely unnecessary.  Furthermore, it doesn't make
a lot of sense to ask a caller to ask SymbolFile which is tied
to Module X to find types for Module Y, but that possibility
was open with the previous interface.  By removing this
parameter from the API, it makes it harder to use incorrectly
as well as easier for an implementor to understand what it
needs to do.

Zachary Turner c0a246afbe [SymbolFile] Remove the SymbolContext parameter from FindNamespace.
Every callsite was passing an empty SymbolContext, so this parameter
had no effect.  Inside the DWARF implementation of this function,
however, there was one codepath that checked members of the
SymbolContext.  Since no call-sites actually ever used this
functionality, it was essentially dead code, so I've deleted this
code path as well.

Zachary Turner ffc1b8fd76 [SymbolFile] Rename ParseFunctionBlocks to ParseBlocksRecursive.
This method took a SymbolContext but only actually cared about the
case where the m_function member was set.  Furthermore, it was
intended to be implemented to parse blocks recursively despite not
documenting this in its name.  So we change the name to indicate
that it should be recursive, while also limiting the function
parameter to be a Function&.  This lets the caller know what is
required to use it, as well as letting new implementers know what
kind of inputs they need to be prepared to handle.

James Y Knight 786558882c Update GettingStarted guide to recommend that people use the new
official Git repository.

Remove the directions for using git-svn, and demote the prominence of
the svn instructions.

Also, fix a few other issues while I'm in there:

* Mention LLVM_ENABLE_PROJECTS more.
* Getting started doesn't need to mention test-suite, but should
  mention clang and the other projects.
* Remove mentions of "configure", since that's long gone.

I've also adjusted a few other mentions of svn to point to github, but
have not done so comprehensively.

Lang Hames 46f0a97e2c [Object] Return a symbol_iterator, rather than a basic_symbol_iterator, from
MachOObjectFile::getSymbolByIndex.

ObjectFile derivatives should prefer symbol_iterator/SymbolRef over
basic_symbol_iterator/BasicSymbolRef where possible, as the former
retain their link to the ObjectFile (rather than a SymbolicFile) and provide
more functionality.

No test for this: Existing code is working, and we don't have (m)any libObject
unit tests. I'll think about how we can test more systematically going forward.

Jordan Rupprecht 93bfb99ffc [llvm-ar] Flatten thin archives.
Summary:
Normal behavior for GNU ar is to flatten thin archives when adding them to another thin archive, i.e. add the members directly instead of nesting the archive.

Some refactoring done as part of this patch to ease things:
 - Consolidate `addMember`/`addLibMember` methods
 - Rename `addMember` to `addChildMember` to make it more visibly different at the call site that an archive child is passed instead of a regular member
 - Pass in a separate vector and splice it back into position instead of passing a vector + optional Pos (which makes expanding libs tricky)

This fixes PR37530 as raised by https://github.com/ClangBuiltLinux/linux/issues/279.

Disable tests requiring sunrpc when the relevant headers are missing.
In order to accommodate that, move the header check
from sanitizer_common to base-config-ix, and define the check result
as a global variable there.  Use it afterwards both for definition
needed by sanitizer_common, and to control 'sunrpc' test feature.

While at it, remove the append_have_file_definition macro that was used
only once, and no longer fits the split check-definition.

Summary:
UB isn't nice. It's cool and powerful, but not nice.

[[ https://wg21.link/p1007r3 | P1007R3: std::assume_aligned ]] / http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1007r2.pdf says:
```
We propose to add this functionality via a library function instead of a core language attribute.
...
If the pointer passed in is not aligned to at least N bytes, calling assume_aligned results in undefined behaviour.
```

This differential teaches clang to sanitize all the various variants of this assume-aligned attribute.

Requires D54588 for LLVM IRBuilder changes.
The compiler-rt part is D54590.

For that, i need to access the final pointer on which the check is performed,
and the actual `icmp` that does the check.

The alternative to this would be to fully re-implement this in clang.
