Bill Wendling e106c34817 LLVM doesn't always optimize away the four loads from this:
(__m128){ p[0], p[1], p[2], p[3] }

which produces really bad code. This could be done in instcombine, but it's
probably better to do it in the front-end instead.

Alexis Hunt 5a7fa250ab Properly parse the 'default' and 'delete' keywords.
They are actually grammatically considered definitions and parsed
accordingly.

This fixes the outstanding bugs regarding defaulting functions after
their declarations.

We now really nicely diagnose the following construct (try it!)

int foo() = delete, bar;

Still todo: Defaulted functions other than default constructors
            Test cases (including for the above construct)

Alexis Hunt f92197cf96 Make it so that we actually generate definitions for explicitly
defaulted default constructors.

As it happens, making sure that we handle out-of-line defaulted
functions properly will involved making sure that we actually parse them
correctly, so that's coming after.

Greg Clayton fdeb15635b Cleaned up the ABI::PrepareTrivialCall() function to take three argument
pointers:

        virtual bool
        PrepareTrivialCall (Thread &thread, 
                            lldb::addr_t sp,
                            lldb::addr_t functionAddress,
                            lldb::addr_t returnAddress, 
                            lldb::addr_t *arg1_ptr,
                            lldb::addr_t *arg2_ptr,
                            lldb::addr_t *arg3_ptr) const = 0;

Prior to this it was:

        virtual bool
        PrepareTrivialCall (Thread &thread, 
                            lldb::addr_t sp,
                            lldb::addr_t functionAddress,
                            lldb::addr_t returnAddress, 
                            lldb::addr_t arg,
                            lldb::addr_t *this_arg,
                            lldb::addr_t *cmd_arg) const = 0;

This was because the function that called this slowly added more features to
be able to call a C++ member function that might have a "this" pointer, and 
then later added "self + cmd" support for objective C. Cleaning this code up
and the code that calls it makes it easier to implement the functions for
new targets.

The MacOSX_arm::PrepareTrivialCall() is now filled in and ready for testing.

Douglas Gregor 373af9bc5d When checking for the necessary 'template<>' headers based on the
nested of an out-of-line declaration, only require a 'template<>'
header for each enclosing class template that hasn't been previously
specialized; previously, we were requiring 'template<>' for enclosing
class templates and members of class templates that hadn't been
previously specialized. Fixes <rdar://problem/9422013>.

Jason W Kim c09e726455 Address the last bit of relocation flag related divergence betweeen
LLVM and binutils.

With this patch, there are no functional differences between the .o
produced directly from LLVM versus the .s to .o via GNU as, for relocation tags
at least, for both PIC and non-PIC modes.

Because some non-PIC reloc tags are used (legally) on PIC, so IsPCRel flag is
necessary but not sufficient to determine whether the overall codegen mode is
PIC or not. Why is this necessary? There is an incompatibility of how relocs
are emitted in the .rodata section.  Binutils PIC likes to emit certain relocs
as section relative offsets.  Non-PIC does not do this.

So I added a hidden switch on the ELFObjectwriter "-arm-elf-force-pic" which
forces the objectwriter to pretend that all relocs are for PIC mode.


Todo: Activate ForceARMElfPIC to true if -relocation-model=pic is selected
on llc.

Todo: There are probably more issues for PIC mode on ARM/MC/ELF...

Todo: Existing tests in MC/ARM/elf-reloc*.ll need to be converted over to .s 
tests as well as expanded to cover the gamut.

Greg Clayton 31f1d2f535 Moved all code from ArchDefaultUnwindPlan and ArchVolatileRegs into their
respective ABI plugins as they were plug-ins that supplied ABI specfic info.

Also hookep up the UnwindAssemblyInstEmulation so that it can generate the
unwind plans for ARM.

Changed the way ABI plug-ins are handed out when you get an instance from
the plug-in manager. They used to return pointers that would be mananged
individually by each client that requested them, but now they are handed out
as shared pointers since there is no state in the ABI objects, they can be
shared.

Jakob Stoklund Olesen 31a0b5e2f0 Avoid hoisting spills when looking at a copy from another register that is also
about to be spilled.

This can only happen when two extra snippet registers are included in the spill,
and there is a copy between them. Hoisting the spill creates problems because
the hoist will mark the copy for later dead code elimination, and spilling the
second register will turn the copy into a spill.
