Reid Kleckner aac43c6a77 Handle errors in lambda prototype instantiation correctly
Previously we would attempt to build a TypeSourceInfo for a null type,
and then we would forget to pop the function scope before returning an
error.

Richard Smith 01014cee76 Remove code that tries to avoid transforming non-dependent call operator types
for lambda expressions. That can't ever work; we need to transform the
parameters in order to create new ones in the new call operator context.

Fixes a rejects-valid when transforming a context containing a
lambda-expression that uses its function parameters in C++14 mode.

Richard Smith 2e32155b58 Instantiate exception specifications when instantiating function types (other
than the type of a function declaration). We previously didn't instantiate
these at all! This also covers the pathological case where the only mention of
a parameter pack is within the exception specification; this gives us a second
way (other than alias templates) to reach the horrible state where a type
contains an unexpanded pack, but its canonical type does not.


This is a re-commit of r219977:

r219977 was reverted in r220038 because it hit a wrong-code bug in GCC 4.7.2.
(That's gcc.gnu.org/PR56135, and affects any implicit lambda-capture of
'this' within a template.)


r219977 was a re-commit of r217995, r218011, and r218053:

r217995 was reverted in r218058 because it hit a rejects-valid bug in MSVC.
(Incorrect overload resolution in the presence of using-declarations.)
It was re-committed in r219977 with a workaround for the MSVC rejects-valid.

r218011 was a workaround for an MSVC parser bug. (Incorrect desugaring of
unbraced range-based for loop).

Richard Smith 0f0af19b05 [c++1z] N4295: fold-expressions.
This is a new form of expression of the form:

  (expr op ... op expr)

where one of the exprs is a parameter pack. It expands into

  (expr1 op (expr2onwards op ... op expr))

(and likewise if the pack is on the right). The non-pack operand can be
omitted; in that case, an empty pack gives a fallback value or an error,
depending on the operator.

NAKAMURA Takumi 44d4d9a4cb Don't capture DeclRefExpr::getNameInfo().getInfo(). It returns reference in temporary object.
DeclarationNameInfo::getInfo() returns reference, but DeclRefExpr::getNameInfo() returns temporary DeclarationNameInfo().

It triggered a local crash for me.

Tyler Nowicki c724a83e20 Allow constant expressions in pragma loop hints.
Previously loop hints such as #pragma loop vectorize_width(#) required a constant. This patch allows a constant expression to be used as well. Such as a non-type template parameter or an expression (2 * c + 1).
