merging for overrides. One might want to make a method's availability
in a superclass different from that of its subclass. Fixes

is cast to a boolean. An exception has been made for string literals in
logical expressions to allow the common case of use in assert statements.
bool x;
x = "hi"; // Warn here
void foo(bool x);
foo("hi"); // Warn here
assert(0 && "error");
assert("error); // Warn here

the key function is inline, rather than the original
declaration. Perhaps FunctionDecl::isInlined() is poorly named. Fixes

The solution is to create a new ParseScope(Scope::TemplateParamScope) for each template scope that we want to reenter. (from the outmost to the innermost scope)
This fixes some errors when parsing MFC code with clang.

This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there.
The paths are then passed down to cc1 with -I options (CPATH), added after the normal user-specified include dirs.
Language specific paths are passed via -LANG-isystem and the actual filtering is performed in the frontend.
I tried to match GCC's behavior as close as possible
Fixes PR8971.

It's not valid to remove filters from landingpad instructions, even if we catch
the type. The metadata won't be set up correctly.
Testcase is projects/llvm-test/SingleSource/UnitTests/EH/filter-2.cpp.

constructor. And, actually set the implicitly-defined bit for
implicitly-defined constructors and destructors. Should fix self-host.

OpenCL 6.2.1 says: "Implicit conversions between built-in vector data types are
disallowed." OpenCL 6.2.2 says: "Explicit casts between vector types are not
legal." For example:
uint4 u = (uint4)(1);
int4 i = u; // invalid implicit conversion
int4 e = (int4)u; // invalid explicit conversion

OpenCL is different from AltiVec in the way it supports vector literals. OpenCL
is strict with regards to semantic checks. For example, implicit conversions
and explicit casts between vectors of different types are disallowed.

if the definition has a non-variadic prototype with compatible
parameters. Therefore, the default rule for such calls must be to
use a non-variadic convention. Achieve this by casting the callee to
the function type with which it is required to be compatible, unless
the target specifically opts out and insists that unprototyped calls
should use the variadic rules. The only case of that I'm aware of is
the x86-64 convention, which passes arguments the same way in both
cases but also sets a small amount of extra information; here we seek
to maintain compatibility with GCC, which does set this when calling
an unprototyped function.
