__builtin_astype(): Used to reinterpreted as another data type of the same size using for both scalar and vector data types.
Added test case.

Emit debug info only if there is an insertion point. The debug info should not force an insertion point. Codegen may later on decide to not emit code for some reason, see extensive comment in CodeGenFunction::EmitStmt(), and debug info should not get in the way.

Add unnamed_addr to internal globals which are only used as an operand to memcpy. (Spotted by looking at IR.)

Match llvm-gcc's string literals alignment by forcing alignment on string literals to 1.  This can significantly impact the size of the string data, and as far as I know, the alignment doesn't help performance.  rdar://9078969 .

to be careful to emit landing pads that are always prepared to handle a
cleanup path.  This is correct mostly because of the fix to the LLVM
inliner, r132200.

parameter types to be ill-formed. However, it relies on the
completeness of method parameter types when producing metadata, e.g.,
for a protocol, leading IR generating to crash in such cases.

Since there's no real way to tighten down the semantics of Objective-C
here without breaking existing code, do something safe but lame:
suppress the generation of metadata when this happens.

Fixes <rdar://problem/9123036>.

Skip extra copy from aggregate where it isn't necessary; rdar://problem/8139919 .  This shouldn't make much of a difference at -O3, but should substantially reduce the number of generated memcpy's at -O0.

Originally r130717, but was backed out due to an ObjC regression.

implement __underlying_type properly - with TypeSourceInfo and proper

Fix some problems where functions must be bitcast but we're expecting a llvm::Function of the right type.

in PR9794 to not have an alloca temporary.

generator will give it something sufficient.  This is important because
the mid-level optimizer doesn't know what alignment is required otherwise.

Type::isUnsignedIntegerOrEnumerationType(), which are like
Type::isSignedIntegerType() and Type::isUnsignedIntegerType() but also
consider the underlying type of a C++0x scoped enumeration type.

Audited all callers to the existing functions, switching those that
need to also handle scoped enumeration types (e.g., those that deal
with constant values) over to the new functions. Fixes PR9923 /
