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.

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.

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.

Summary:
Clang calls these functions to produce IR for assume-aligned attributes.
I would like to teach UBSAN to verify these assumptions.
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.

This is the integer sibling to D56011.
There's an additional restriction to only to do this transform in the
case where we don't have extra extracts from the source vector. Without
that, we can fail to match larger horizontal patterns that are more
beneficial than this minimal case. An improvement to the more general
h-op lowering may allow us to remove the restriction here in a follow-up.

Normally, changing the function signatures of C APIs is disallowed,
but as these two are brand new last week, and haven't been released
yet, it is okay in this instance.
As per discussion in D56556, we will not add NameLen arguments to IR
building APIs, for the following reasons:
1. We do not want to deprecate all of the IR building APIs, just to add a
NameLen argument to each one.
2. Consistency is important, so adding it just to new ones is unfortunate.
3. The IR names are completely optional, useful for readability of IR
only. There is no value in ever supporting nul bytes.
