Fix another SROA crasher, PR14601.
This was a silly oversight, we weren't pruning allocas which were used
by variable-length memory intrinsics from the set that could be widened
and promoted as integers. Fix that.
This should fix the following assertion failure:
Assertion failed: (CanSROA), function visitUsers, file

built with clang. When these are defined the lists are defined similar to:
asm(".section .ctors");
STATIC func_ptr __CTOR_LIST__[1] = { (func_ptr) (-1) };
asm(".section .dtors");
STATIC func_ptr __DTOR_LIST__[1] = { (func_ptr) (-1) };
The problem is clang will move the two arrays out of the .ctors and .dtors
sections causing these sections to contain a single null address. By not
defining these macros we use the version of the code that places the arrays
is their sections by using __attribute__((section(".ctors"))) and similar
for .dtors.

When using libc++ headers on FreeBSD, in combination with -std=c++98,
-ansi or -std=c++03, the long long type is not supported. So in this
case, several functions and types, like lldiv_t, strtoll(), are not
declared.
This should make it possible to use the libc++ headers in c++98 mode.
Note: libc++ is originally designed as a c++0x or higher library, so you
should still take care when using it with c++98 or c++03.

X86: fcmov doesn't handle all possible EFLAGS, fall back to a branch

Otherwise it will try to use SSE patterns and fail horribly if sse is

Add a new warning -Wmissing-variable-declarations, to warn about variables
defined without a previous declaration. This is similar to
-Wmissing-prototypes, but for variables instead of functions.
Make sure always-inline functions get inlined. <rdar://problem/12423986>
Without this change, when the estimated cost for inlining a function with
an "alwaysinline" attribute was lower than the inlining threshold, the
getInlineCost function was returning that estimated cost rather than the
special InlineCost::AlwaysInlineCost value. That is fine in the normal
inlining case, but it can fail when the inliner considers the opportunity
cost of inlining into an internal or linkonce-odr function. It may decide
not to inline the always-inline function in that case. The fix here is just
to make getInlineCost always return the special value for always-inline
functions. I ran into this building clang with libc++. Tablegen failed to
link because of an always-inline function that was not inlined. I have been
unable to reduce the testcase down to a reasonable size.
This should fix the link errors that were reported when atf-run was
compiled with clang -stdlib=libc++. In this case, at -O3 optimization,
some calls to basic_ios::clear() were not inlined, even when the
function was marked __always_inline__.
