brokenness in the designated-initializer ASTs. The ASTs were fixed by
Alp Toker's patch (r116098) for PR6955. Fixes PR6537.

completes support for C1X anonymous struct/union init features:

 * Indexed anonymous member initializers should not be expanded. Doing so makes
little sense and would cause unresolvable semantic ambiguity in valid code
(regression introduced by r69153).

 * Subobject initialization of (possibly nested) anonymous members are now
referred to with paths relative to the naming record context, eliminating the
synthesis of incorrect implicit InitListExprs that caused CodeGen to assert.

 * Field lookup was missing a null check in IdentifierInfo comparison which
caused lookup for a known (already resolved) field to match the first unnamed
data member it encountered leading to silent miscompilation.

 * Subobject paths are no longer built using the general purpose
Sema::BuildAnonymousStructUnionMemberPath(). If any corner cases crop up, we
will now assert earlier in Sema instead of passing invalid InitListExprs
through to CodeGen.

Fixes PR6955, from Alp Toker!

callee-saved registers at the end of the lists.  Also prefer to avoid using
the low registers that are in register subclasses required by certain
instructions, so that those registers will more likely be available when needed.
This change makes a huge improvement in spilling in some cases.  Thanks to
Jakob for helping me realize the problem.

Most of this patch is fixing the testsuite.  There are quite a few places
where we're checking for specific registers.  I changed those to wildcards
in places where that doesn't weaken the tests.  The spill-q.ll and
thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch
of live values to force spills on those tests.

preambles:

  - When we rebuild a precompiled preamble, make sure to disable
    skipping anything in the main file; we may have had leftover
    preamble-skipping values in the lexer, which leads to very empty
    preamble. This is a correctness issue.

  - When we rebuild a precompiled preamble, clear out any prior state
    in the Diagnostic object. Otherwise, we might think that there
    were errors when we were building the preamble itself, and
    therefore reject the resulting preamble. This is mainly a
    performance issue.

  - Don't remove old remappings when digging out the remapping for the
    main file. Having the old mappings around does not hurt in the
    common case (later remappings will just overwrite them), and is
    important when we fail to find a preamble: we don't want to have
    removed the remapping, because we'll need it later.
