Fix forwarding of -fpack-struct from driver to CC1, and add a test.

-fpack-struct's handling has changed in CC1 (one of only two flags that needed changing) because the driver treats "-fpack-struct" as a boolean flag, and CC1 (did) treat it as an option with a separated value.

This change causes -fpack-struct=X to be forwarded correctly to -fpack-struct=X instead of erroneously to "-fpack-struct X"

Replace the StringSwitch in AttributeList::getKind(const
IdentifierInfo *) with a static StringMap, improving -fsyntax-only
performance by 1% for the example in <rdar://problem/11004361>.

Replace a ConsumeAnyToken() call with ConsumeToken() when we know
we're looking at a normal token. Tiny positive impact -fsyntax-only

Driver: Turn the default value for -fmath-errno into a proper target hook and disable it by default on more platforms.

For now -fno-math-errno is the default on BSD-derived platforms (Darwin,
DragonFlyBSD, FreeBSD, NetBSD, OpenBSD). If the default is not right for
your platform, please yell. I only verified the result with the default
compilers on Darwin and FreeBSD.

Implement the alternate spellings of attributes aligned (as "align")
and const (as "__const") using tblgen, rather than explicitly hacking
them in.

Fix same line doxycomments so they comment the adjacent field.

Without the '<' prefix in the doxycomment these comments were incorrectly
attached to the proceeding comment on the next line, rather than the
preceeding one.

Introduce the notion of 'ignored' attributes, so that all attributes
we accept are not modeled somehow via Attr.td.
