ab17fb2c98 fix the more complex cases by actually codegen'ing the right expr :)

28bcf1a429 add codegen support for casting an element to a union. 
There are some more complex cases (_Complex and structs)
that I'm still working on.

8ce48d8c10 x86_32 ABI: Don't try and expand structures with bitfields. 
- This is an ABI incompatiblity, but this is not likely to be a huge
   deal in practice. For now we at least generate self consistent code
   instead of crashing.

f85a938985 Fix PR3682 by just disabling a broken assertion. This check should be 
done in sema, and is reflected by the existing PR3258.  In the meantime,
fix PR3682 by disabling a bogus assertion (which doesn't account for + 
operands).

d7d5fdf090 move matching of named operands into AsmStmt class. At the same 
time handle + operands in operand counting, fixing asm.c:t7 to
expand into $2 instead of $1.

cecc21d2f6 Make IRGen compatible with declaring a function with incomplete 
return/argument types.  (The generated IR isn't ideal, but we can't 
really do better in general.)

22fcc24b30 Initial implementation of CodeGen for incomplete function types; fixes 
PR3688.  (The FIXME is a rather big performance issue, but it only 
affects code using this feature, which is relatively rare.)

codegen, until such time as codegen is complete enough to turn on with
-fblocks.

78350edafb Fix for PR3687: use the memory representation for booleans when a 
sub-type describes a memory location, like the pointee type of a pointer
or the element type of an array.

3ef668c27a after going around in circles a few times, finally cave and emit structure 
copies with memcpy instead of memmove.  This matches what GCC does and if it
causes a problem with a particular libc we can always fix it with a target
hook.

e62c0a45dd Improve merging of function declarations. Specifically: 
- When we are declaring a function in local scope, we can merge with
    a visible declaration from an outer scope if that declaration
    refers to an entity with linkage. This behavior now works in C++
    and properly ignores entities without linkage.
  - Diagnose the use of "static" on a function declaration in local
    scope.
  - Diagnose the declaration of a static function after a non-static
    declaration of the same function.
  - Propagate the storage specifier to a function declaration from a
    prior declaration (PR3425)
  - Don't name-mangle "main"
