Add some more PS4 driver settings related to rtti and exceptions.
Summary:
The PS4 defaults to -fno-rtti, and has to have rtti enabled when enabling
exceptions.
This commit makes clang add the -fno-rtti by default on the PS4, unless
-frtti was passed in.
It also diagnoses misuses for the PS4:
- Exceptions need rtti. Warn and enable rtti if no rtti flag was passed,
error if -fno-rtti was passed.
I also added a more general warning for when -fno-rtti is the default
(currently it's only on the PS4) and the vptr sanitizer is on.
Fixed a few tests, due to different flag order when passing cc1 arguments.

PECOFF: Do not use LayoutPass and instead use simpler one.
The LayoutPass is one of the slowest pass. This change is to skip
that pass. This change not only improve performance but also improve
maintainability of the code because the LayoutPass is pretty complex.
Previously we used the LayoutPass to sort all atoms in a specific way,
and reorder them again for PE/COFF in GroupedSectionPass.
I spent time on improving and fixing bugs in the LayoutPass (e.g.
r193029), but the pass is still hard to understand and hard to use.
It's better not to depend on that if we don't need. For PE/COFF, we
just wanted to sort atoms in the same order as the file order in the
command line.
The feature we used in the LayoutPass is now simplified to
compareByPosition function in OrderPass.cpp. The function is just 5
lines.
This patch changes the order of final output because it changes the
sort order a bit. The output is still correct, though.

This does not scale well to having multiple sets of Root nodes, as the

Don't create multiple mergeable sections with -fdata-sections.
ELF has support for sections that can be split into fixed size or
null terminated entities.
Since these sections can be split by the linker, it is not necessary
to split them in codegen.
This reduces the combined .o size in a llvm+clang build from
202,394,570 to 173,819,098 bytes.
The time for linking clang with gold (on a VM, on a laptop) goes
from 2.
250089985 to 1.
383001792 seconds.
The flip side is the size of rodata in clang goes from 10,926,785
to 10,929,345 bytes.
The increase seems to be because of http://sourceware.org/bugzilla/show_bug.cgi?id=17902.

MS ABI: Implement proper support for setjmp
On targets which use the MSVCRT, setjmp is a macro which expands to
_setjmp or _setjmpex.
_setjmp and _setjmpex have a secret, hidden argument which is not listed
in the function prototype on X64 and WoA. This hidden argument always
seems to be the frame pointer.
_setjmpex isn't used on X86, _setjmp is magically replaced with a call
to _setjmp3. The second argument is zero for 'normal' setjmp/longjmp
pairs, otherwise it is a count of additional variadic arguments. This
is used when setjmp appears inside of a try or __try.
It is not safe to use a pointer to setjmp because _setjmp, _setjmpex and
_setmp3 are not compatible with setjmp.

Use the existing build configuration parameter ENABLE_BACKTRACE to compile out all pretty stack trace support when backtraces are disabled.
This has the nice secondary effect of allowing LLVM to continue to build
for targets without __thread or thread_local support to continue to work
so long as they build without support for backtraces.
