John McCall e6e622e789 Only apply -fvisibility-inlines-hidden to definitions. Apparently 
isInlined() just gives meaningless results for non-definitions.

John McCall c273f24196 Better solution: calculate the visibility of functions and variables 
independently of whether they're definitions, then teach IR generation to
ignore non-explicit visibility when emitting declarations.  Use this to
make sure that RTTI, vtables, and VTTs get the right visibility.

John McCall 36cd5cc150 GCC faithfully calculates visibility for variables independently of 
whether it's a declaration or not, then ignores that information for
declarations unless it was explicitly given.  It's not totally clear
how that should be mapped into a sane system, but make an effort.

Douglas Gregor 5ef9e33137 Make the deserialization of macro definitions lazy, so that we can 
load identifiers without loading their corresponding macro
definitions. This is likely to improve PCH performance slightly, and
reduces deserialization stack depth considerably when using
preprocessor metaprogramming.

to get references to X86_MMXTy out of the common code.

John McCall 37bb6c9832 Restore r117644, this time properly ignoring -fvisibility and type visibility 
for namespace-scope variable declarations.

Apply visibility in IR gen to variables that are merely declared
and never defined.  We were previously emitting these with default
visibility unless they were declared with private_extern.

Ignore global visibility settings when computing visibility for
a declaration's context, and key several conditions on whether a
visibility attribute exists anywhere in the hierarchy as opposed
to whether it exists at the current level.
