marked as AlwaysInline or ForceInline.
This moves us to what gcc does with -fno-inline. The attribute approach
was discussed to be better than switching to InlineAlways inliner in presence
of LTO.

Per discussion with Anna a /long/ time ago, it was way too easy to misuse
BlockCall: because it inherited from AnyFunctionCall (through SimpleCall),
getDecl() was constrained to return a FunctionDecl, and you had to call
getBlockDecl() instead. This goes against the whole point of CallEvent
(to abstract over different ways to invoke bodies of code).
Now, BlockCall just inherits directly from CallEvent. There's a bit of
duplication in getting things out of the origin expression (which is still
known to be a CallExpr), but nothing significant.

libstdc++v4.6. This is quite hard to test directly, so we test for it by
checking a known missing feature in that version that was added in v4.7.
This should prevent users from upgrading Clang but not GCC and hosting
with a too-old GCC's libstdc++ and getting strange and hard to debug
errors when we switch to C++11 by default.
Also, switch several of the macros I introduced to use AC_LANG_SOURCE
rather than AC_LANG_PROGRAM as we don't need configure's help writing
our main function (and we don't need such a function at all for most of
the tests).

MSVC on x64 requires that we create image relative symbol
references to refer to RTTI data. Seeing as how there is no way to
explicitly make reference to a given relocation type in LLVM IR, pattern
match expressions of the form &foo - &__ImageBase.

Disabling remote MCJIT tests on ARM again, as they're still failing when
self-hosting on ARM, despite all my tests. At least now we have more info
on what message it's breaking and what is going on. Investigating.

a subprocess invocation which is pretty significant on Windows. It also
likely saves a bunch of thrashing the host machine needlessly. Finally
it makes the tests much more predictable and less dependent on the host.
For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to
thwart the host detection adding it into the compilation. By runnig CC1
directly we don't have to deal with such oddities.

test the CC1 layer.
This actually uncovered that the test semes to no longer be passing for
the reasons intended. =[ The name of the test would lead me to believe
that it should be testing the semantics of noreturn in the static
analyzer.... but there are in fact no -verify assertions about noreturn
that i can find. And the noreturn checker is no longer in 'alpha.core'.
It is in 'core.builtins'. The test *does* have one assertion for a null
dereference warning. This *also* isn't in 'alpha.core', but the driver
inserts a pile of other checker packages, including 'core' which has
this warning.
So I have switch the RUN line to actually do the minimal thing that this
test currently exercises, but someone who works on the static analyzer
should probably look at this and either nuke it or move it to actually
check the noreturn behavior.

Way back in r129652 we tried to avoid emitting an empty block at -O0
for switch cases that did nothing but break. This led to a poor
debugging experience as reported in PR9796, so we disabled the
optimization for -O0 but left it in for higher optimization levels in
r154420.
Since the whole point of this was to improve -O0, it's silly to keep
the complexity at all.
