Duncan Sands 76d6217906 Verify metadata harder. In particular, check that module 
level metadata does not have any function local operands.
This would have caught the problem found in PR6112.

Torok Edwin 63dd86352e Fix PR6910. 
Limit alignment in SmallVector 8, otherwise GCC assumes 16 byte alignment.
opetaror new, and malloc only return 8-byte aligned memory on 32-bit Linux,
which cause a crash if code is compiled with -O3 (or -ftree-vectorize) and some
SmallVector code is vectorized.

Douglas Gregor 9225b02096 When performing partial ordering of class template partial 
specializations, substitute the deduced template arguments and check
the resulting substitution before concluding that template argument
deduction succeeds. This marvelous little fix makes a bunch of
Boost.Spirit tests start working.

Douglas Gregor 33dcc2e34d It turns out that we *can* end up having to display template argument

Douglas Gregor d170206761 Teach __builtin_offsetof to compute the offsets of members of base 
classes, since we only warn (not error) on offsetof() for non-POD
types. We store the base path within the OffsetOfExpr itself, then
evaluate the offsets within the constant evaluator.

Douglas Gregor 882211c1da Completely reimplement __builtin_offsetof, based on a patch by Roberto 
Amadini.

This change introduces a new expression node type, OffsetOfExpr, that
describes __builtin_offsetof. Previously, __builtin_offsetof was
implemented using a unary operator whose subexpression involved
various synthesized array-subscript and member-reference expressions,
which was ugly and made it very hard to instantiate as a
template. OffsetOfExpr represents the AST more faithfully, with proper
type source information and a more compact representation.

OffsetOfExpr also has support for dependent __builtin_offsetof
expressions; it can be value-dependent, but will never be
type-dependent (like sizeof or alignof). This commit introduces
template instantiation for __builtin_offsetof as well.

There are two major caveats to this patch:

  1) CodeGen cannot handle the case where __builtin_offsetof is not a
  constant expression, so it produces an error. So, to avoid
  regressing in C, we retain the old UnaryOperator-based
  __builtin_offsetof implementation in C while using the shiny new
  OffsetOfExpr implementation in C++. The old implementation can go
  away once we have proper CodeGen support for this case, which we
  expect won't cause much trouble in C++.

  2) __builtin_offsetof doesn't work well with non-POD class types,
  particularly when the designated field is found within a base
  class. I will address this in a subsequent patch.

Fixes PR5880 and a bunch of assertions when building Boost.Python
tests.
