First round of fixes for the x86 fixes for the x86 move accumulator from/to memory offset instructions.

-Assembly parser now properly check the size of the memory operation specified in intel syntax. So 'mov word ptr [5], al' is no longer accepted.
-x86-32 disassembly of these instructions no longer sign extends the 32-bit address immediate based on size.
-Intel syntax printing prints the ptr size and places brackets around the address immediate.

Known remaining issues with these instructions:
-Segment override prefix is not supported. PR16962 and PR16961.
-Immediate size should be changed by address size prefix.

Summary:
Previously the backend wouldn't get to see the underlying GlobalValue
that corresponds to the template argument because it would be hidden by
a cast at the IR level.  Instead strip the pointer casts off of the
value until we see the underlying GlobalValue.

a non-constant GEP.

I don't have any test case that demonstrates this, Nadav (indirectly)
pointed this out in code review. I'm not sure how possible it is to
contrive a test case for the current users of this code that triggers
the bad issue sadly.

We currently emit labels with the prefix Lllvm$workaround$fake$stub$ if
the target's MCAsmInfo has getLinkOnceDirective() mapped to something
interesting.  This was apparently a work around introduced in r31033 for
binutils that we don't need anymore.

llvm-svn: 189187

I need to add the rest of these to the list or else to delay putting
out the actual stub until later in code generation when I know if
the external function ever got emitted

Resubmit this patch. The target triple needs to be added to the test so that 
clang does not tell the backend the wrong target when the host is BSD. There
is a clang bug in here somewhere that I need to track down. At Mips this
has been filed internally as a bug.

This completes the subsystem name parsing to support the identifiers that the
Microsoft link.exe linker supports.  "windows" and "console" are left as the
first items as they are the expected common paths.

clang already had a mstrict-align which mentiones "Force all memory
accesses to be aligned (ARM only)". On gcc arm this is controlled by
-munaligned-access / -mno-unaligned-access. Add the gcc versions to
the frontend and make -mstrict-align and alias to -mno-unaligned-access
and only show it in clang -cc1 -help.

Since the default value for unaligned accesses / strict alignment
depends on the tripple, both the enable and disable flags are added.
If both are set, the no-unaligned-access is used.

This patch adds the -ffixed-r9 flag to clang to instruct llvm to
globally preserve the contents of r9. The flag is added to the newly
created ARM specific group.

While at it, also place marm / mno-thumb in that group.

Summary:
This allows us to handle the general case where a non-type template
