clang-format: Add support for a space after @property

Mozilla and WebKit seem to use a space after @property (verified by
grepping their codebases) so we turn this on there as well.

Change by Christian Legnitto. Thank you!

Intrin.h: include setjmp.h to get a jmp_buf definition

This makes sure that the ms-intrin.cpp test passes by providing

cast into a boolean true value.  This warning will catch code like:

clang-cl: Better error message when trying to compile stdin (PR18640)

We should suggest using /Tc or /Tp to set the input type, instead of
erroneously suggesting -x, which isn't a clang-cl flag.

Short-circuit a couple of queries (and avoid corrupting
the linkage cache) when type-checking static local
variables.

There's a very deep problem here where the linkage of
a declaration can suddenly massively change as soon as
it's given a typedef name; these fixes, while optimizations
in their own right, are really just targeted workarounds.
