3751991798 Adapt to llvm debuginfo change: use DITypeArray instead of DIArray in some places

b1a7a7af1b Reference-count inlined functions to keep them alive until we emit debug 
info for them and generally clean up the inline scope handling a bit.
Fix the debug scope handling for all clients of SILCloner, especially
the SIL-level spezializers and inliners.
This also adds a ton of additional assertions that will ensure that
future optimization passes won't mess with the debug info in a way that
could confuse the LLVM backend.

2df66cf8c4 Implement inline scopes for the performance inliner. 
Mandatory-inlined (aka transparent functions) are still treated as if they
had the location and scope of the call site. <rdar://problem/14845844>
Support inline scopes once we have an optimizing SIL-based inliner

Patch by Adrian Prantl.

98383a5c6a Debug info: Use WeakVHs in DIRefMap so LLDB can safely invoke IRGen more 
than once (at least as far as IRGenDebugInfo is concerned).

No new testcases, but it comes with new assertions.

b1d9d186a0 [please update llvm] Debug info: Use the mangled name as unique identifier 
for types where possible.

We use the DICompositeType's UniqueIdentifier field to store the mangled
name, the name field to store the base name and Apple-llvm will emit the
unique identifier as DW_AT_name if RunTimeLang == Swift. This way the
metadata format is compatible between swift and non-Apple clang.
As bonus, we get mangled-name-based type uniquing for swift.
