Now that the relevant tests use -mconstructor-aliases and the missing
features have been implemented, we can just drop this.

This adds a new option -fprofile-sample-use=filename to Clang. It

This patch fixes PR8264. Duplicate qualifiers already are diagnozed,
now the same diagnostics is issued for duplicate function specifiers.

The problem was that given
template<typename T>
struct foo {
~foo() {}
};
template class foo<int>;
We would produce a alias, creating a comdat with D0 and D1, since the symbols
have to be weak. Another TU is not required to have a explicit template
instantiation definition or an explict template instantiation declaration and
for
template<typename T>
struct foo {
~foo() {}
};
foo<int> a;
we would produce a comdat with only one symbol in it.

Like GCC, this re-uses the 'f' constraint and a new 'w' print-modifier:
asm ("ldi.w %w0, 1", "=f"(result));
Unlike GCC, the 'w' print-modifer is not _required_ to produce the intended
output. This is a consequence of differences in the internal handling of
the registers in each compiler. To be source-compatible between the
compilers, users must use the 'w' print-modifier.
MSA registers (including control registers) are supported in clobber lists.

The xcore llvm backend does not handle 8 byte alignment viz:
"%BadAlignment = alloca i64, align 8"
So getPreferredTypeAlign() must never overalign.

The original decls are created when used. The replacements are created at the
end of the TU in reverse order.
This makes the original order far better for testing. This is particularly
important since the replacement logic could be used even when
-mconstructor-aliases is not used, but that would make many tests hard to read.
This is a fixed version of r194357 which handles replacing a destructor with
another which is an alias to a third one.

See http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-November/033369.html for discussion on cfe-dev.
This fix explicitly checks whether we are within the declcontext of a lambda's call operator - which is what I had intended to be true (and assumed would be true if getCurLambda returns a valid pointer) before checking whether a lambda can capture the potential-captures of the innermost lambda.
A deeper fix (that addresses why getCurLambda() returns a valid pointer when perhaps it shouldn't?) - as proposed by Richard Smith in http://llvm.org/bugs/show_bug.cgi?id=17877 - has been suggested as a FIXME.
Patch was LGTM'd by Richard (just barely :)

substitution failure, allow a flag to be set on the Diagnostic object,
to mark it as 'causes substitution failure'.
Refactor Diagnostic.td and the tablegen to use an enum for SFINAE behavior
rather than a bunch of flags.

Hopefully Richard won't notice this terrible egregiocity - clearly the work of a malevolent poltergeist - fixed now ;)

No Functionality change.
This refactoring avoids having to call getCurLambda right after PushLambdaScope, to obtain the LambdaScopeInfo that was created during the call to PushLambdaScope.

The assert this patch deletes was valid only when aliasing D2 to D1, not when
looking at a base class. Since the assert was in the path where we had already
decided to not produce an alias, just drop it.

Summary:
Currently with clang:
$ clang -O20 foo.c
error: invalid value '20' in '-O20'
With the patch:
$ clang -O20 foo.c
warning: invalid value '20' in '-O20'. Fall back on value '3'

clang-cl adds these, so this makes the tests a bit more realistic. These are the

removed.

It is not safe to emit alias to undefined (not supported by ELF or COFF), but

Before, existing code in the form of:

whether we can safely lower a conditional operator to select was insufficient.
I've left a large comment in place to explaining the sort of problems that this
transform can encounter in clang in the hopes of discouraging others from
reimplementing it wrongly again in the future. (The test should also help with
that, but it's easy to work around any single test I might add and think that
your particular implementation doesn't miscompile any code.)

Unlike an alias a rauw is always safe, so we don't need to avoid this
optimization when the replacement is not know to be available in every TU.

The `print` function has been available as a __future__ import since

This makes it consistent with -fdump-record-layouts, which was moved to
outs() in r186219. My reasoning for going with stdout is that when one
of these options is present, the layouts are really a program output,
and shouldn't be interleaved with diagnostics, which are on stderr.
