DwarfDebug class could generate the same (inlined) DIVariable twice:
1) when trying to find abstract debug variable for a concrete inlined instance.
2) when explicitly collecting info for variables that were optimized out.
This change makes sure that this duplication won't happen and makes
Clang pass "gdb.opt/inline-locals" test from gdb testsuite.

This flag sets the 'fp-contract' mode, which controls the formation of fused
floating point operations. Available modes are:
- Fast: Form fused operations anywhere.
- On: Form fused operations where allowed by FP_CONTRACT. This is the default
mode.
- Off: Don't form fused operations (in future this may be relaxed to forming
fused operations where it can be proved that the result won't be
affected).
Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off'
modes are equivalent.

very simple semantic analysis that just builds the AST; minor changes for lexer
to pick up source locations I didn't think about before.
Comments AST is modelled along the ideas of HTML AST: block and inline content.
* Block content is a paragraph or a command that has a paragraph as an argument
or verbatim command.
* Inline content is placed within some block. Inline content includes plain
text, inline commands and HTML as tag soup.

that the migrator handles) but return their instances as 'id', resulting
in the compiler resolving 'objectForKey:' as the method from NSDictionary.
When checking if we can convert to subscripting syntax, check whether
the receiver is a result of a class method from a hardcoded list of
such classes. In such a case return the specific class as the interface
of the receiver.

The include list was cleaned up a bit as well.
Also the test case was modified to test for both
big and little patterns.

This may turn out to be a controversial change, due to string literals being
uniqued at link time, but Apple's docs only say "The compiler makes such
object constants unique on a per-module basis..."[1] without actually saying
what a "module" is. (It's not a clang module.) Furthermore, this uniqueness
guarantee often can't be guaranteed once the string has been passed through
framework code.
If this does turn out very controversial, we could downgrade this to a
DefaultError warning for strings, and leave it as a true Error for other
kinds of literals.

the MatchFinder in the upcoming ASTMatcher patch).
