The 'a', 'c', and 'd' constraints on i386 mean a 32-bit register. We cannot
place a 64-bit value into the 32-bit register. Error out instead of causing the
compiler to spew general badness.

- New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature
- Builtin macro '__RTM__' is defined if RTM feature is enabled
- RTM intrinsic header is added and introduces 3 new intrinsics, namely
'_xbegin', '_xend', and '_xabort'.
- 3 new builtins are added to keep compatible with gcc, namely
'__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'.
- Test cases for pre-defined macro and new intrinsic codegen are added.

Haiku does not support this (yet). Leaving it set to true leads to
configure scripts detecting __thread being available and Clang emitting
code for it, resulting in binaries the runtime_loader will refuse to
load.

ELF subtarget.
The existing description string is moved from PPC64TargetInfo to its
DarwinTargetInfo subclass, to avoid any changes to the Darwin ABI.
PPC64TargetInfo now has two possible description strings: one for FreeBSD,
which requires 8-byte alignment, and a default string that requires
16-byte alignment.
I've added a test for PPC64 Linux to verify the 16-byte alignment. If
somebody wants to add a separate test for FreeBSD, that would be great.
Note that there is a companion patch to update the alignment information
in LLVM, which I am committing now as well.

This code checks the ASM string to see if the output size is able to fit within
the variable specified as the output. For instance, scalar-to-vector conversions
may not really work. It's on by default, but can be turned off with a flag if
you think you know what you're doing.
This is placed under a flag ('-Wasm-operand-widths') and flag group ('-Wasm').

Because PNaCl bitcode must be target-independent, it uses some
different bitcode representations from other targets (e.g. byval and
sret for structures). This means that without additional type
information, it cannot meet some native ABI requirements for some
targets (e.g. passing structures containing unions by value on
x86-64). To allow generation of code which uses the correct native
ABIs, we also support triples such as x86_64-nacl, which uses
target-dependent IR (as opposed to le32-nacl, which uses byval and
sret).
To allow interoperation between the two types of code, this patch adds
a calling convention attribute to be used in code compiled with the
target-dependent triple, which will generate code using the le32-style
bitcode. This calling convention does not need to be explicitly
supported in the backend because it determines bitcode representation
rather than native conventions (the backend just needs to undersand
how to handle byval and sret for the Native Client OS).
This patch implements __attribute__((pnaclcall)) to generate calls in
bitcode according to the le32 bitcode conventions, an attribute which
is accepted by any Native Client target, but issues a warning
otherwise.

AAPCS ABI Section 7.1.4 [1] specifies that va_list
should be defined as struct __va_list { void *__ap;};
And in C++, it is defined in namespace std.

Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".
Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

to define all macros for MIPS targets. Remove redundant virtual function
getArchDefines(). Two virtual functions for this task are really too much.

Instead of adding it to each individual subclass in
Targets.cpp, simply check the appropriate target
values.
Where before it was only on x86_64 and ppc64, it's now
also defined on mips64 and nvptx64.
Also add a bunch of negative tests to ensure it is *not*
defined on any other architectures while we're here.

AVX). Currently, if no aligned attribute is specified the alignment of a vector is
inferred from its size. Thus, very large vectors will be over-aligned with no
benefit. Target owners should set this target max.

For some reason GCC decided to call the feature rdrnd instead of rdrand,
which requires translating it for LLVM.
