Handle include directive with comments.  It turns out that in this case comments are not coming in source order.  Instead of trying to std::sort() comments (which can be costly), just remove comments that are not in order.

to be generic across architectures. It has the
following description in the gnu sources:

    Negate the immediate constant

Several Architectures such as x86 have local implementations
of operand modifier 'n' which go beyond the above description
slightly. This won't affect them.

Affected files:

    lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp
        Added 'n' to the switch cases.

    test/CodeGen/Generic/asm-large-immediate.ll
        Generic compiled test (x86 for me)

    test/CodeGen/Mips/asm-large-immediate.ll
        Mips compiled version of the generic one

Update comments accordingly.

CallGraph's recursive visitor only needs to collect declarations; their
bodies will be processed later on. RecursiveASTVisitor will recurse on
the bodies if the definition is provided along with declaration.
Optimize, by not recursing on any of the statements.

This now correctly covers, I believe, all the pointer types:
* 'any' pointers (both function and data normal pointers and ObjC object pointers)
* member pointers (both function and data)
* block pointers

to be generic across architectures. It has the
following description in the gnu sources:

    Substitute immediate value without immediate syntax

Several Architectures such as x86 have local implementations
of operand modifier 'c' which go beyond the above description
slightly. To make use of the generic modifiers without overriding
local implementation one can make a call to the base class method
for AsmPrinter::PrintAsmOperand() in the locally derived method's 
"default" case in the switch statement. That way if it is already
defined locally the generic version will never get called.

This change is needed when test/CodeGen/generic/asm-large-immediate.ll
failed on a native Mips board. The test was assuming a generic
implementation was in place.

Affected files:

    lib/Target/Mips/MipsAsmPrinter.cpp:
        Changed the default case to call the base method.
    lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp
        Added 'c' to the switch cases.
    test/CodeGen/Mips/asm-large-immediate.ll
        Mips compiled version of the generic one

move some typedefs so that we don't polute the llvm namespace. this should appease the GCC buildbots

llvm-svn: 158924

hopefully fix the buildbots:  some tests have wrong definitions of malloc and were crashing this code on 64 bits machines

port the BoundsChecking patch to the new MemoryBuiltin API (i.e., remove most of the code from here).
Remove the alloc_size.ll test until we settle on a metadata format that makes everyone happy..

llvm-svn: 158920

 - provide more extensive set of functions to detect library allocation functions (e.g., malloc, calloc, strdup, etc)
 - provide an API to compute the size and offset of an object pointed by

Move a few clients (GVN, AA, instcombine, ...) to the new API.
This implementation is a lot more aggressive than each of the custom implementations being replaced.

The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages.

Among other fundamental advantages, we start to get the checking logic
for when a file is missing from the CMake build, and this caught one
missing file already! More fun details in the LLVM commit corresponding
to this one.

Note that the LLVM commit and this one most both be applied, or neither.
Sorry for any skew issues.

Makefiles, the CMake files in every other part of the LLVM tree, and
sanity.

This should also restore the output tree structure of all the unit
tests, sorry for breaking that, and thanks for letting me know.

The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages:

- No more weird directory stripping in the unittest macro, allowing it
  to be used more readily in other projects.
- No more directory prefixes on all the source files.
- Allows correct and precise use of LLVM's per-directory dependency
  system.
- Allows use of the checking logic for source files that have not been
  added to the CMake build. This uncovered a file being skipped with
  CMake in LLVM and one in Clang's unit tests.
- Makes Specifying conditional compilation or other custom logic for JIT
  tests easier.

It did require adding the concept of an explicit 'optional' source file
to the CMake build so that the missing-file check can skip cases where
the file is *supposed* to be missing. =]

This is another chunk of refactoring the CMake build in order to make it
usable for other clients like CompilerRT / ASan / TSan.

Note that this is interdependent with a Clang CMake change.
