Revert r119838 "Don't warn for empty 'if' body if there is a macro that expands to nothing"
...
and use a better and more general approach, where NullStmt has a flag to indicate whether it was preceded by an empty macro.
Thanks to Abramo Bagnara for the hint!

Don't warn for empty 'if' body if there is a macro that expands to nothing, e.g:
...
if (condition)
CALL(0); // empty macro but don't warn for empty body.

Calculate the value kind of an expression when it's created and
...
store it on the expression node. Also store an "object kind",
which distinguishes ordinary "addressed" l-values (like
variable references and pointer dereferences) and bitfield,
@property, and vector-component l-values.
Currently we're not using these for much, but I aim to switch
pretty much everything calculating l-valueness over to them.
For now they shouldn't necessarily be trusted.

Improve the tracking of source locations for parentheses in constructor calls.
...
This adds them where missing, and traces them through PCH. We fix at least one
bug in the extents found by the Index library, and make a lot of refactoring
tools which care about the exact formulation of a constructor call easier to
write. Also some minor cleanups to more consistently follow the friend pattern
instead of the setter pattern when rebuilding a serialized AST.
Patch originally by Samuel Benzaquen.
