Reapplies r159406 with minor cleanup. The regressions appear to have been spurious.

attached to a declaration in the completion string.

Since extracting comments isn't free, a new code completion option is
introduced.

A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

and multi-line nature of this test. I don't really feel like bugging
this kind of edge-case, so just put it on one line and use single
quotes. With this, every test *really* passes with the built-in shell
test runner.

through my perl nets.

With this, the test suite passes even if I force it to run with the
built-in shell test logic, except for a test which REQUIREs shell.

This is directly cloned from the logic in the TCL test bits of lit.
Hopefully will fix most of the windows build bot fallout.

  - Changed isSingleNumber method behaviour. Now this flag is calculated on demand.
IntegersSubsetMapping
  - Optimized diff operation.
  - Replaced type of Items field from std::list with std::map.
  - Added new methods:
    bool isOverlapped(self &RHS)
    void add(self& RHS, SuccessorClass *S)
    void detachCase(self& NewMapping, SuccessorClass *Succ)
    void removeCase(SuccessorClass *Succ)
    SuccessorClass *findSuccessor(const IntTy& Val)
    const IntTy* getCaseSingleNumber(SuccessorClass *Succ)
IntegersSubsetTest
  - DiffTest: Added checks for successors.
SimplifyCFG
  Updated SwitchInst usage (now it is case-ragnes compatible) for
    - SimplifyEqualityComparisonWithOnlyPredecessor
    - FoldValueComparisonIntoPredecessors

This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]

a pipeline, and then a positive assertion via grep, use two RUN lines
instead.

Supporting these complex ideas of 'success' and 'failure' across
multiple stages of a pipeline is brittle in the shell world, and would
block switching to ShTest format; it only worked due to contrivances
introduced by the TclTest format.

Writing this as two separate RUN lines seems clearer in any event.

This is another step toward completely removing TclTests from lit.

use FileCheck.

Aside from removing a dependence on TCL-style quoting, this also makes
the tests ... significantly more robust. =] It would be really, *really*
great of the maintainer(s) of the CellSPU backend went through and
systematically rewrite these tests to use FileCheck. There are a lot
more that have nearly this bad of abuses.

Another step along the path to a TclTest-free testsuite.

just provide and reference separate input files from an Inputs
subdirectory. This pattern works very well in the Clang tree and is
easier to understand in my opinion. It also has fewer limitations and
will remove one particularly annoying use of TCL-style {} quoting from
the testsuite.

Also teach the LLVM lit configuration to avoid recursing into 'Inputs'
subdirectories. This wasn't required for the previous 'Inputs'
subdirectories used due to fortuitous suffix patterns.

This is the first step to completely removing support for TCL-style tests.

1) DIContext is now able to return function name for a given instruction address (besides file/line info).
2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag).

For some targets a structure named __va_list_tag is built to help define
the __builtin_va_list type.  However, __va_list_tag was not being treated as a
predefined type thus causing problems when serializing the AST.  This commit
fixes that oversight by adding the necessary support to treat __va_list_tag
as a predefined type.
