Douglas Gregor d6225d304e Introduce a new libclang API to determine the platform availability of
a given entity, so that we can tell when the entity was
introduced/deprecated/obsoleted on each platform for which we have an
annotation. Addresses <rdar://problem/11365715>.

Rafael Espindola 3c9d9479b0 Process attributes in the order they appear in the source code. This make clang
match gcc behavior for two conflicting visibilities in the same decl. It also
makes handling of dllimport/dllexport more natural.

As a bonus we now warn on the dllimport in

void __attribute__((dllimport)) foo13();
void __attribute__((dllexport)) foo13();

as does gcc.

Johnny Chen 5ec8fcbf0c Fix the problem that 'help breakpoint set' is printing a lot of redundant lines.
Correctly specify the LLDB_OPT_SET's that the 'shlib' command option belongs to by using a newly added macro like this:

    #define LLDB_OPT_NOT_10 ( LLDB_OPT_SET_FROM(1, 10) & ~LLDB_OPT_SET_10 )

Johnny Chen ddb149069e Add an -F option to the redo.py script to selectively re-run only those failed sessions whose filenames contain the component(s)
specified.  For example:

    ./redo.py -F x86_64 -n 2012-05-07-15_28_24

will redo the failed sessions under the 2012-05-07-15_28_24 directory, but only for session names which contain 'x86_64' in it.

Jakob Stoklund Olesen 98595b5a61 Coalesce subreg-subreg copies.
At least some of them:

  %vreg1:sub_16bit = COPY %vreg2:sub_16bit; GR64:%vreg1, GR32: %vreg2

Previously, we couldn't figure out that the above copy could be
eliminated by coalescing %vreg2 with %vreg1:sub_32bit.

The new getCommonSuperRegClass() hook makes it possible.

This is not very useful yet since the unmodified part of the destination
register usually interferes with the source register. The coalescer
needs to understand sub-register interference checking first.

This is temporary until we settle on how to make the main RecursiveASTVisitor safe.
There are some modifications on the original version, to avoid extreme memory usage
when compiling for release.

Jakob Stoklund Olesen 3c52f0281f Add an MF argument to TRI::getPointerRegClass() and TII::getRegClass().
The getPointerRegClass() hook can return register classes that depend on
the calling convention of the current function (ptr_rc_tailcall).

So far, we have been able to infer the calling convention from the
subtarget alone, but as we add support for multiple calling conventions
per target, that no longer works.

Jakob Stoklund Olesen 65a6dafc8d Add TRI::getCommonSuperRegClass().
This function is a generalization of getMatchingSuperRegClass() to the
symmetric case where both sides are using a sub-register index. It will
find a super-register class and sub-register indexes that make this
diagram commute:

                                   PreA
                       SuperRC  ---------->  RCA

                          |                   |
                          |                   |
                     PreB |                   | SubA
                          |                   |
                          |                   |
                          V                   V

                         RCB    ----------> SubRC
                                   SubB

This can be used to coalesce copies like:

  %vreg1:sub16 = COPY %vreg2:sub16; GR64:%vreg1, GR32: %vreg2

The chdir is not the perfect fix, as it is thread hostile. The
real fix will be to make -working-dir work correctly, which will
take time to implement. Before that, the tooling library cannot
be used concurrently.

Richard Smith 9ca6461f5a When we suppress an error due to SFINAE, stash the diagnostic away with the
overload candidate, and include its message in any subsequent 'candidate not
viable due to substitution failure' note we may produce.

To keep the note small (since the 'overload resolution failed' diagnostics are
often already very verbose), the text of the SFINAE diagnostic is included as
part of the text of the note, and any notes which were attached to it are
discarded.

There happened to be spare space in OverloadCandidate into which a
PartialDiagnosticAt could be squeezed, and this patch goes to lengths to avoid
unnecessary PartialDiagnostic copies, resulting in no slowdown that I could
measure. (Removal in passing of some PartialDiagnostic copies has resulted in a
slightly smaller clang binary overall.) Even on a torture test, I was unable to
measure a memory increase of above 0.2%.
