Ted Kremenek 9d6eb40ce7 Fix leak in CXXNewExpr where the SubExprs array would get allocated directly using 'new[]' instead of the allocator associated with ASTContext.

John McCall 81472e34b2 Make this test not rely on the system <limits.h>. Hopefully fixes the 
MSVC build.

Ted Kremenek 2c809308ca Allocate the SubExprs array in ObjCMessageExpr using the allocator associated with ASTContext. This fixes yet another leak (<rdar://problem/7639260>).

Chris Lattner 524138176d add a new MCInstPrinter::getOpcodeName interface, when it is 
implemented, llvm-mc --show-inst now uses it to print the
instruction opcode as well as the number.

Chris Lattner b8af65ed0b improve encoding information for branches. We now know they have 
8 or 32-bit immediates, which allows the new encoder to handle
them.

Chris Lattner ddeceae839 make getFixupKindInfo return a const reference, allowing

Jakob Stoklund Olesen 28139f0043 It is always good to do a cross-class join when the large register has a tiny interval. 
Also avoid division by zero.

Douglas Gregor 7eeb59752a When AST merging for record declarations fails, warn about the 
incompatibility and show where the structural differences are. For
example:

struct1.c:36:8: warning: type 'struct S7' has incompatible definitions
in different translation units
struct S7 { int i : 8; unsigned j : 8; } x7;
       ^
struct1.c:36:33: note: bit-field 'j' with type 'unsigned int' and length 8 here
struct S7 { int i : 8; unsigned j : 8; } x7;
                                ^
struct2.c:33:33: note: bit-field 'j' with type 'unsigned int' and length 16 here
struct S7 { int i : 8; unsigned j : 16; } x7;
                                ^

There are a few changes to make this work:
  - ASTImporter now has only a single Diagnostic object, not multiple
  diagnostic objects. Otherwise, having a warning/error printed via
  one Diagnostic and its note printed on the other Diagnostic could
  cause the note to be suppressed.
  - Implemented import functionality for IntegerLiteral (along with
  general support for statements and expressions)

Jeffrey Yasskin 8a30324e51 Make Kaleidoscope not link against the interpreter, since that didn't 
work anyway (Interpreter::getPointerToFunction doesn't return a
callable pointer), and improve the error message when an
ExecutionEngine can't be created.

John McCall be089fa86b Suppress warnings if their instantiation location is in a system header, not 
their spelling location.  This prevents warnings from being swallowed just
because the caret is on the first parenthesis in, say, NULL.

This is an experiment;  the risk is that there might be a substantial number
of system headers which #define symbols to expressions which inherently cause
warnings.  My theory is that that's rare enough that it can be worked
around case-by-case, and that producing useful warnings around NULL is worth 
it.  But I'm willing to accept that I might be empirically wrong.

Ted Kremenek d31b2637ab Patch by Cristian Draghici: 
Enhance the printf format string checking when using the format
specifier flags ' ', '0', '+' with the 'p' or 's' conversions (since
they are nonsensical and undefined).  This is similar to GCC's
checking.

Also warning when a precision is used with the 'p' conversin
specifier, since it has no meaning.

Chris Lattner 5a4ec879bf fix a really nasty bug I introduced in r95693: r12 (and r12d, 
r12b, etc) also encodes to a R/M value of 4, which is just
as illegal as ESP/RSP for the non-sib version an address.

This fixes x86-64 jit miscompilations of a bunch of programs.

Anders Carlsson 5d40c6f658 Check in the beginnings of my new vtable layout builder idea. 
Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code.

I've also added a very simple new vtable layout test case.
