Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.

Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

Chris Lattner e76b95ae15 make the x86-32 backend specify a byval alignment, even when the
code generator will do it.  With this patch, clang compiles the example
in PR9794 to not have an alloca temporary.

Chris Lattner 44c2b90556 Fix x86-64 byval passing to specify the alignment even when the code
generator will give it something sufficient.  This is important because
the mid-level optimizer doesn't know what alignment is required otherwise.

John McCall e0fda7377e The 0.98 revision of the x86-64 ABI clarified a lot of things, some
of which break strict compatibility with previous compilers.  Implement
one of them and then immediately opt out on Darwin.

Anton Korobeynikov 231e875b5c Implement ARM pcs attribute. Basically it's another way of calling convention selection (AAPCS or
AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86.

In particular, all library functions should always be AAPCS regardless of floating point ABI used.

Bill Wendling ec9d2633f1 When we adjust the inline ASM type, we need to take into account an early
clobber with the 'y' constraint. Otherwise, we get the wrong return type and an
assert, because it created a '<1 x i64>' vector type instead of the x86_mmx
type.

Bill Wendling 812f4b123e The "gcc.dg/compat/vector-1 -m32" test was broken after the MMX rewrite. The
function parameters weren't converted to use the correct type (x86_mmx). Add a
check, similar to the one in llvm-gcc, to see if we need the x86_mmx type for
that function parameter. If so, it coerces the type to be that.

Chris Lattner a09e8efd1f Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

Daniel Dunbar b34b08098c IRgen/ABI/ARM: Trust the backend to pass vectors correctly for the given ABI.
- Therefore, we can lower out the NEON wrapper structs and pass the vectors
   directly. This makes a huge difference in the cleanliness of the IR after
   optimization.
 - I will trust, but verify, via future ABITest testing (for APCS-GNU, at
   least).

Daniel Dunbar ed23de3348 IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types get passed
with a non-default-stack-ABI-alignment (of 16).
 - This fixes the ABI convenient, but breaks codegen since we now have
   underaligned arguments. Marginal improvement overall though, and will be
   fixed in next commit.

Daniel Dunbar 8a6c91ff76 IRgen/x86_32/Linux: Linux seems to align all stack objects to 4 bytes, unlike
Darwin. Checked vs the handiest Linux llvm-gcc I had around, someone on Linux is
welcome to investigate more.

Chris Lattner d426c8eae3 fix rdar://8360877 a really nasty miscompilation in Boost.Xpressive
caused by my ABI work.  Passing:

struct outer {
  int x;
  struct epsilon_matcher {} e;
  int f;
};

as {i32,i32} isn't safe, because the offset of the second element
needs to be at 8 when it is interpreted as a memory value.
