Richard Smith 3501895863 Revert r345562: "PR23833, DR2140: an lvalue-to-rvalue conversion on a glvalue of type" 
This exposes a (known) CodeGen bug: it can't cope with emitting lvalue
expressions that denote non-odr-used but usable-in-constant-expression
variables. See PR39528 for a testcase.

Reverted for now until that issue can be fixed.

Richard Smith d2e69dfddb PR23833, DR2140: an lvalue-to-rvalue conversion on a glvalue of type 
nullptr_t does not access memory.

We now reuse CK_NullToPointer to represent a conversion from a glvalue
of type nullptr_t to a prvalue of nullptr_t where necessary.

Anders Carlsson 898b1fb1e2 Pass a -I flag when compiling nullptr.cpp so the typeinfo header can be found. This should fix the errors seen on the bot.

Douglas Gregor c934bc840c Perform overload resolution when static_cast'ing from a 
pointer-to-member-to-derived to a pointer-to-member-to-base. Fixes
PR6072.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
