Daniel Dunbar 034299ef25 IRGen: Move the auxiliary data structures tracking AST -> LLVM mappings out of CodeGenTypes, to per-record CGRecordLayout structures.
- I did a cursory check that this was perf neutral, FWIW.

John McCall d9c7c6568e Introduce a new kind of derived-to-base cast which bypasses the need for
null checks, and make sure we elide null checks when accessing base class
members.

Rafael Espindola 2e42fec3a0 Fix PR6473.
Clang's support for weakref is now better than llvm-gcc's :-)

We don't introduce a new symbol and we correctly mark undefined references weak only if there is no
definition or regular undefined references in the same file.

Daniel Dunbar d004918ccb IRgen: Add CreateIRTemp, which creates a temporary alloca but with type converted "not-for-memory". Dunno a better name.

John McCall 7538eec67b When emitting an aggregate into a temporary, make sure we set the alignment
on the alloca.

The fact that codegen makes this class of bug so wonderfully easy to make is
embarrassing.

Anders Carlsson 5bd8d19291 More vtable layout dumper improvements. Handle destructors, dump the complete function type of the member functions (using PredefinedExpr::ComputeName.

Daniel Dunbar a7566f163a IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing.
- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

Daniel Dunbar 3d33fab7fc Reapply r95393, without the change to CGExpr. I was wrong in assuming that the
element type always matched the converted LLVM type for ExprType.

John McCall ab26cfa58d Standardize the parsing of function type attributes in a way that
follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

conceptually correct. Review appreciated (Chris, Eli, Anders).

Charles Davis 5a5473f0f8 Now that we store calling conventions in the types, use them instead of
getting the calling convention from the target function, which may or may not
exist. Fixes PR5280.

Daniel Dunbar 363589bded IRgen: Use hasAggregateLLVMType instead of isSingleValueType() for cases that
need to deal with aggregates specially; this is consistent with the rest of IRgen.

Also, simplify EmitParmDecl and don't worry about using Decl::getNameAsString.

Anders Carlsson 824e0613de When binding an lvalue to a reference, we always need to pop temporaries.
With this fix, and the other fixes committed today a make check-all with a clang-built LLVM now gives:

Expected Passes    : 6933
Expected Failures  : 46
Unsupported Tests  : 40
Unexpected Failures: 27

which means that we pass 99.96% of all tests :) The resulting 27 tests are all LLVMC tests and seem to be because of differences in the clang and gcc drivers.

Anders Carlsson db78f0ad04 Add a new EmitLValueForFieldInitialization that will be used for initializing fields (and reference type fields in particular).
