Use this to fix the leak of DeserializedDeclsDumper and DeserializedDeclsChecker
in FrontendAction (found by LSan), PR19560.
The "delete this" bool is necessary because both PCHGenerator and ASTUnit
return the same object from both getDeserializationListener() and
getASTMutationListener(), so ASTReader can't just have a unique_ptr.
It's also not possible to just let FrontendAction (or CompilerInstance) own
these listeners due to lifetime issues (see comments on PR19560).
Finally, ASTDeserializationListener can't easily be refcounted, since several of
the current listeners are allocated on the stack.
Having this bool isn't ideal, but it's a pattern that's used in other places in
the codebase too, and it seems better than leaking.

This addresses an existing FIXME item in the driver. The code model flag was
parsed in the actual tool rather than in the driver. This was problematic since
the value may be invalid. In that case, we would silently treat it as a default
value in non-assert builds, and abort in assert builds. Add a check in the
driver to validate that the value being passed is valid, and if not provide a
proper error message.

C++. This seems like a pointless (and indeed harmful) restriction to me, so
I've suggested removing it to -core and disabled this diagnostic by default.

Previously we calculated the shift amount based upon DataLayout::getTypeAllocSizeInBits.
This will only work for legal types - types such as i24 that are created as part of
structs for bitfields will return "32" from that function. Change to using
getTypeSizeInBits.
It turns out that AArch64 didn't run across this problem because it always returned
[1 x i64] as the type for a bitfield, whereas ARM64 returns i64 so goes down this
(better, but wrong) codepath.

While constructing ObjC Interface types we might create the declaration
of some normal C++ types, thus adding things to the ReplaceMap. Make
sure we process the ReplaceMap after the ObjC interfaces.
In theory we know at this point, since we're at the end of the TU, that
we won't be upgrading any declarations to definitions, so we could just
construct non-temporary nodes, but that would require extra state in
CGDebugInfo to conditionalize the creation of declaration nodes which
seems annoying/more work than is appropriate.

In cases where a struct must, according to the AAPCS, not be split between
general purpose and floating point registers, we use
ABIArgInfo::getExpandWithPadding to add the padding arguments. However,
ExpandWithPadding does not work if the struct contains bitfields, so we
instead must use ABIArgInfo::getDirect.

This makes it easier to see where a global ctor comes from, and it also makes
ASan's init order analyzer output easier to understand. gcc does this too,
but only in -fPIC mode for some reason. Don't do this for constructors with
explicit init priority.
Also prepend "sub_" before the 'I', that way regular constructors stay
lexicographically after symbols with init priority (because
ord('s') > ord('I')). gold seems to ignore the name of constructor symbols,
and ld only looks at the symbol if it includes an init priority, which this
patch doesn't change.

Reverting r208106 to reapply r208065 with a fix for the regression. The
issue was that the enum tried to be built even if the declaration hadn't
been constructed for debug info - presenting problems for enum templates
and typedefs of enums with names for linkage purposes.
Original commit message:
This regressed a little further 208055 though it was already a little
broken.
While the requiresCompleteType optimization should be implemented here.
Future (possibly near future) work.

BugReport doesn't take ownership of the bug type, so let the checker own the
