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.

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

use of property-dot syntax using 'super' as receiver
is 'void'. This fixes a bug in generating correct
API for setter call. Fixes radar 8203426.

There is no need to use separate dir name for AT_comp_dir attribute. Using absolute path for filename allows clients to query complete file location info from gdb breakpoints. Save constructed full file name.

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.
