Workaround for libstdc++4.6 <atomic> bug: make comment more explicit about what's going on, per Sean Silva's suggestion.

This appears to be consistent with GCC's implementation of the same warning
under -Wparentheses. Suppressing a << b + c for cases where 'a' is a user
defined type for compatibility with C++ stream IO. Otherwise suggest
parentheses around the addition or subtraction subexpression.

(this came up when MSVC was complaining (incorrectly, so far as I can tell)
about a perceived violation of this within the LLVM codebase, PR14001)

the surrounding namespace. In this one special case, permit the namespace to be
reopened as inline, and patch up the name lookup tables to match.

crtfastmath.o contains routines to set the floating point flags to a faster,
unsafe mode. Linking it in speeds up code dealing with denormals significantly
(PR14024).

For now this is only enabled on linux where I can test it and crtfastmath.o is
widely available. We may want to provide a similar file with compiler-rt
eventually and/or enable it on other platforms too.

For GNU attributes, instead of reusing attribute source 
location for the scope location, use SourceLocation() since 
GNU attributes don not have scope tokens.

This may be slightly more efficient and is definitely more readable.

Fix r165005: The lexical DeclContext is not the right place to make a decision about whether we need to call tryAddTopLevelDecl or not. That call should be made when the DeclContext's redeclaration context is the translation unit.

This parameter is useless because nowhere used explicitly and always

Most of the pieces for this were already in place, but a proper EmitVAArg
is needed for aggregates and complex numbers to be handled.  Although the
va_list for 64-bit PowerPC SVR4 consists of GPRs 3 through 10 together with
the overflow portion of the parameter save area, we can treat va_list as
pointing to contiguous memory for all parameters, since the back end forces
the parameter GPRs to memory for varargs functions.

There is no need at this time to model parameters and return values beyond
what the DefaultABIInfo provides.

* nullptr used to be mapped to ERROR, now mapped to nullptr
* integral was missing
* expressions now have their own error message, so they won't reach
  this. Map them to ERROR.

Note that clang usually crashes before emitting this diagnostic anyway
(see PR13984), so this change alone doesn't have an observable effect.
It makes the code more correct though.

llvm-svn: 165095

This matches what's done in ItaniumMangle and makes it a bit easier
to implement mangling for more expressions. Also use the slightly nicer
"not yet implemented" error message from there.

No functionality change (except for the different error message).
