Richard Smith 8c6eeb9599 Replace "failed template argument deduction" diagnostic with something useful 
in the one case where we've already factored out a reason code.

Richard Smith 0db1ea5f68 Fix overload resolution for the initialization of a multi-dimensional 
array from a braced-init-list. There seems to be a core wording wart
here (it suggests we should be testing whether the elements of the init
list are implicitly convertible to the array element type, not whether
there is an implicit conversion sequence) but our prior behavior appears
to be a bug, not a deliberate effort to implement the standard as written.

Douglas Gregor f4cc61d525 When testing whether we can perform copy or move initialization, be 
sure to supply an initialization location. Fixes <rdar://problem/11951661>.

Douglas Gregor 0f5c1c0127 Allow a conversion from the empty initializer list {} to an 
std::initializer_list<T> so long as <T> is known. This conversion has
identity rank.

Douglas Gregor 0e60cd78cc When performing template argument deduction for an initializer list, 
be sure to perform the argument type adjustments in
[temp.deduct.call]p2, e.g., array decay.

And, when performing these deductions in the context of 'auto', make
sure that we're deducing the P' in std::initializer_list<P'> rather
than the whole initializer list.

Together, this makes code like

  for( auto s : {"Deferred", "New", "Open", "Review"}) { }

work properly.

Sebastian Redl d74dd49065 Proper initializer list support for new expressions and type construct expressions. Array new still missing.

Sebastian Redl 09edce0400 Minor fixups for auto deduction of initializer lists. 
Fix some review comments.
Add a test for deduction when std::initializer_list isn't available yet.
Fix redundant error messages. This fixes and outstanding FIXME too.

Sebastian Redl 42acd4a05b Auto deduction support for std::initializer_list, including for-range support. This means you can now write: 
for (int i : {1, 4, 512, 23, 251}) {}
