Bob Wilson e1223fb583 Attempt to fix llvm-gcc build. It was crashing when building gcov.o for an
ARM cross-compiler on x86, because the MMO size did not match the type size.
This fixes the MMO size and also the size of the stack object to match the
type size.

Argyrios Kyrtzidis ca0d0cd3b9 Implement -Wpadded and -Wpacked.
-Wpadded warns when undesired padding is introduced in a struct. (rdar://7469556)
-Wpacked warns if a struct is given the packed attribute, but the packed attribute has no effect
  on the layout or the size of the struct. Such structs may be mis-aligned for little benefit.

The warnings are emitted at the point where layout is calculated, that is at RecordLayoutBuilder.
To avoid calculating the layouts of all structs regardless of whether they are needed or not,
I let the layouts be lazily constructed when needed. This has the disadvantage that the above warnings
will be emitted only when they are used for IR gen, and not e.g with -fsyntax-only:

$ cat t.c
struct S {
  char c;
  int i;
};
void f(struct S* s) {}

$ clang -fsyntax-only -Wpadded t.c
$ clang -c -Wpadded t.c -o t.o
t.c:3:7: warning: padding struct 'struct S' with 3 bytes to align 'i' [-Wpadded]
  int i;
      ^
1 warning generated.

This is a good tradeoff between providing the warnings and not calculating layouts for all
structs in case the user has enabled a couple of rarely used warnings.

Chris Lattner bd85725341 Fix an inconsistency in the x86 backend that led it to reject "calll foo" on
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.

Greg Clayton 4f432e719b Added some comments explaining why we currently have to manually set CXXRecordDecl variables. This is because SEMA is actually calling the accessors that should be built into the CXXRecordDecl class.

Johnny Chen 9c48b8d79c Added a subtest to exercise the capability of lldb Python objects to print
themselves.  Right now, it tests a breakpoint both before and after it has been
resolved.

Updated lldbtest.TestBase.expect() with an additional keyword argument 'exe' (
default to True), which if set to False, will treat the mandatory first argument
as just the string to be matched/or not-matched against the golden input.
