v2f32 as legal in 32-bit mode. It is just as terrible there,
but I just care about x86-64 and noone claims it is valuable
in 64-bit mode.

Some of the invariant checks for creating Record/Enum types don't hold true during PCH reading.
Introduce more suitable ASTContext::getRecordType() and getEnumType().

Before this commit, visible decls added before deserialization were ignored.
This was not an issue since name lookup (that usually comes before the addition) forces deserialization
but it is an issue for lazily declared class implicit members.
We can use a PCH'ed <string> now.

Currently, adding it to visible decls of a PCH'ed translation unit has no effect because
adding visible decls before deserialization has no effect (the decls won't be visible).
This will be fixed in a future commit; then it will force deserialization of visible decls, so avoid pointlessly installing it.

contain all the same information that their Types do, we will fall back to
traversing the Types instead. The default TypeLoc visitor calls the matching
Type visitor so that existing clients should continue to work with no change.
Also adds element traversal to the ExtVectorType.

second round of low-level interface squeeze-out:
making all of CallInst's low-level operand accessors
private
If you get compile errors I strongly urge you to
update your code.
I tried to write the necessary clues into the
header where the compiler may point to, but no
guarantees. It works for my GCC.
You have several options to update your code:
- you can use the v2.8 ArgOperand accessors
- you can go via a temporary CallSite
- you can upcast to, say, User and call its
low-level accessors if your code is definitely
operand-order agnostic.
If you run into serious problems, please
comment in below thread (and back out this
revision only if absolutely necessary):

Type hierarchy. Without this, TypeLocNodes.def will give you wrong type
hierarchy information (claiming that ObjCObjectTypeLoc is the base of
ObjCInterfaceTypeLoc, which it wasn't).

Also adds a getKnownValue() method to SValuator, which gets the integer value of an SVal if it is known to only have one possible value. There are more places in the code that could be using this, but in general we want to be dealing entirely in SVals, so its usefulness is limited.
The only visible functionality change is that extents are now honored for any DeclRegion, such as fields and Objective-C ivars, rather than just variables. This shows up in bounds-checking and cast-size-checking.

ObjC pointers were easy enough (as far as the ABI is concerned, they're
just pointers to structs), but I had to invent a new mangling for block
pointers. This is particularly worrying with the Microsoft ABI, because
it is a vendor-specific ABI; extending it could come back to bite us
later when MS extends it on their own (and you know they will).

module lldbtest.py and refactored the existing test cases to derive from the
abstract base class lldbtest.TestBase.
MOdified the test driver (dotest.py and dotest.pl) to set up additional
PYTHONPATH component for locating the lldbtest module, which sits in the same
directory.

Only actual functions get mangled correctly; I don't know how to fix it for
function pointers yet. Thanks to John McCall for the hint.
Also, mangle anonymous tag types. I don't have a suitable testcase yet; I have
a feeling that that's going to need support for static locals, and I haven't
figured out exactly how MSVC's scheme for mangling those works.

prepare IR for execution in the target. Wired the
expression command to use this IR transformer when
conversion to DWARF fails, and wired conversion to
DWARF to always fail (well, we don't generate any
DWARF...)

declarations for implicit default constructors, copy constructors,
copy assignment operators, and destructors. On a "simple" translation
unit that includes a bunch of C++ standard library headers, we
generate relatively few of these implicit declarations now:
4/159 implicit default constructors created
18/236 implicit copy constructors created
70/241 implicit copy assignment operators created
0/173 implicit destructors created
And, on this translation unit, this optimization doesn't really
provide any benefit. I'll do some more performance measurements soon,
but this completes the implementation work for <rdar://problem/8151045>.
