-fopenmp in the link step on Linux. There is probably more tweaking that
will need to take place to get good support for linking the relevant
libraries on all Linux distributions and/or on other platforms, but this
get's the ball moving and allows Clang to build programs which contain
OpenMP pragmas that can be safely ignored by a compiler that doesn't
implement them, and yet makes direct calls into the OpenMP runtime.

Also adding more tests.

We can now keep the formatting of something like:

static SomeType type = { aaaaaaaaaaaaaaaaaaaa, /* comment */
                         aaaaaaaaaaaaaaaaaaaa /* comment */,
                         /* comment */ aaaaaaaaaaaaaaaaaaaa,
                         aaaaaaaaaaaaaaaaaaaa, // comment
                         aaaaaaaaaaaaaaaaaaaa };

Note that the comment in the first line is handled like a trailing line comment
as that is likely what the user intended.

r172140 changed the formatter to produce "-(id) foo" instead of "- (id)foo"
in google style, with a link to
http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml#Method_Declarations_and_Definitions
as reference.  But now that I look at that link again, it seems I didn't
read it very carefully the first time round.

This is inspired by a number of false positives in real code, including
PR14968. I've added test cases reduced from these false positives to
test/Sema/unused-expr.c, as well as corresponding test cases that pass the
offending expressions as arguments to a no-op macro to ensure that we do warn
there.

This also removes my previous tweak from r166522/r166534, so that we warn on
unused cast expressions in macro arguments.

There were several test cases that were using -Wunused-value to test general
diagnostic emission features; I changed those to use other warnings or warn on
a macro argument expression. I stared at the test case for PR14399 for a while
with Richard Smith and we believe the new test case exercises the same
codepaths as before.

Move the early if-conversion pass into this group.

ILP optimizations usually need to find the right balance between
register pressure and ILP using the MachineTraceMetrics analysis to
identify critical paths and estimate other costs. Such passes should run
together so they can share dominator tree and loop info analyses.

Besides if-conversion, future passes to run here here could include
expression height reduction and ARM's MLxExpansion pass.

The Mips RDHWR (Read Hardware Register) instruction was not 
tested for assembler or dissassembler consumption. This patch
adds that functionality.

if we can see the elements of the arrays.

for example:

 NSDictionary *dict = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"1", @"2", nil] forKeys:[NSArray arrayWithObjects:@"A", @"B", nil]];

-->

 NSDictionary *dict = @{ @"A" : @"1", @"B" : @"2" };
