Eli Friedman 62f3ef2b53 [CGCall] Annotate references with "align" attribute.
If we're going to assume references are dereferenceable, we should also
assume they're aligned: otherwise, we can't actually dereference them.

Reid Kleckner 0a6096bab2 [mingw] Don't mangle thiscall like fastcall etc
GCC does not mangle it when it is not explicit in the source.  The
mangler as currently written cannot differentiate between explicit and
implicit calling conventions, so we can't match GCC. Explicit thiscall
conventions are rare, so mangle as if the convention was implicit to be
as ABI compatible as possible.

Also fixes some tests using %itanium_abi_triple in some configurations
as a side effect.

Fixes PR40107.

Reid Kleckner f5f6290899 Mangle calling conventions into function pointer types where GCC does
Summary:
GCC 5.1 began mangling these Windows calling conventions into function
types, since they can be used for overloading. They've always been
mangled in the MS ABI, but they are new to the Itanium mangler. Note
that the calling convention doesn't appear as part of the main
declaration, it only appears on function parameter types and other
types.

Fixes PR39860
