Turn struct-path aware TBAA on by default.
Use -no-struct-path-tbaa to turn it off.
This is the same as r191695, which was reverted because it depends on a
commit that has issues.

TBAA: use the same format for scalar TBAA and struct-path aware TBAA.
An updated version of r191586 with bug fix.
Struct-path aware TBAA generates tags to specify the access path,
while scalar TBAA only generates tags to scalar types.
We should not generate a TBAA tag with null being the first field. When
a TBAA type node is null, the tag should be null too. Make sure we
don't decorate an instruction with a null TBAA tag.
Added a testing case for the bug reported by Richard with -relaxed-aliasing
and -fsanitizer=thread.

Don't use mangleCXXRTTIName in TBAA for C code.
With r185721, calling mangleCXXRTTIName on C code will cause crashes.
This commit fixes crashes on C testing cases when turning on struct-path TBAA.
For C code, we simply use the Decl name without the context. This can
cause two different structs having the same name, and may cause inaccurate but
conservative alias results.

Pretty up the emission of field l-values and use volatile and TBAA when
loading references as part of that. Use 'char' TBAA when accessing
(immediate!) fields of a may_alias struct; fixes PR9307.
