22326a10a7 dissolve some more complexity: make the x86-64 abi lowering code 
compute its own preferred types instead of having CGT compute
them then pass them (circuituously) down into ABIInfo.

458b2aaee0 now that ABIInfo depends on CGT, it has trivial access to such 
things as TargetData, ASTContext, LLVMContext etc.  Stop passing
them through so many APIs.

2b03797222 cave in to reality and make ABIInfo depend on CodeGenTypes. 
This will simplify a bunch of code, coming up next.

f4ba08aeaf pass argument vectors in a type that corresponds to the user type if 
possible.  This improves the example to pass <4 x float> instead of
<2 x double> but we still get awful code, and still don't get the
return value right.

4c1e484f39 fix PR7714 by not referencing off the end of a struct when passed by value in 
x86-64 abi.  This also improves codegen as well.  Some refactoring is needed of
this code.

ba80390307 When creating a jump destination, its scope should be the scope of the 
enclosing normal cleanup, not the top of the EH stack.  I'm *really*
surprised this hasn't been causing more problems.

4fac280618 Merge PCHWriterDecl.cpp's isRequiredDecl and CodeGenModule::MayDeferGeneration into a new function, 
DeclIsRequiredFunctionOrFileScopedVar.

This function is part of the public CodeGen interface since it's essentially a CodeGen predicate that is also
needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes.
This fixes current (and avoids future) codegen-from-PCH bugs.

268ad093a7 Untangle filename/dirname confusion. Store constructed strings on the side. Avoid use of Path.makeAbsolute(). 
DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are:

$ clang foo.c -g
  DW_AT_name - foo.c
  DW_AT_comp_dir - `pwd`

$ clang one/two/foo.c -g
  DW_AT_name - one/two/foo.c
  DW_AT_comp_dir - `pwd`

$ clang /tmp/one/foo.c -g
  DW_AT_name - /tmp/one/foo.c
  DW_AT_comp_dir - empty

5cc2c8b9c3 Vectors are not integer types, so the type system should not classify 
them as such. Type::is(Signed|Unsigned|)IntegerType() now return false
for vector types, and new functions
has(Signed|Unsigned|)IntegerRepresentation() cover integer types and
vector-of-integer types. This fixes a bunch of latent bugs.

Patch from Anton Yartsev!

0884a60eb5 Keep track of artificial scopes introduced by line directives. For example, 
#line 41 "bar.c"
  dummy (1, i);
#line 24 "bar.h"
  i = f2 (i);
#line 44 "bar.c"
