were performing name lookup for template names in C/ObjC and always
finding nothing. Turn off such lookup unless we're in C++ mode, along
with the check that determines whether the given identifier is a
"current class name", and assert that we don't make this mistake
again.

Add manual ISD::OR fastisel selection routines. TableGen is no longer autogen them after 93152 and 93191.

codegen has no apparent problem with the trunc version of this, because it turns
into a simple subreg idiom

(fixes radar 6969189).

trunc has multiple uses.  Codegen is not able to coalesce the subreg case 
correctly and so this leads to higher register pressure and spilling (see PR5997).

This speeds up 256.bzip2 from 8.60 -> 8.04s on my machine, ~7%.

Allow VLAs in C++ if in GNU mode (GNU C++ permits them).  Clang can now compile LanguageKit, although the resulting code crashes (although not in any of the functions that use VLAs).

Implement the same interface as already available for dominators.

latter may (eventually) perform multiple levels of desugaring (thus
breaking the newly-added tests) and the former is faster. Thanks, John!

they redefine is a class-name but not a typedef-name, per C++0x
[dcl.typedef]p4. The code in the test was valid C++98 and is valid
C++0x, but an unintended consequence of DR56 made it ill-formed in
C++03 (which we were luck enough to implement). Fixes PR5455.
