r273271 changed the RUN line of the regression test to use
-march=cyclone instead of -mtriple=aarch64-none-none.

This caused a change in the output syntax for the ext

The removal of legacy code to support long-deprecated debugger support library
resulted in some whitespace changes. Comments from that legacy code were made

Summary:
Fix the computation of the offsets present in the scopetable when using the
SEH (__except_handler4).

This patch added an intrinsic to track the position of the allocation on the
stack of the EHGuard. This position is needed when producing the ScopeTable.

```
    struct _EH4_SCOPETABLE {
        DWORD GSCookieOffset;
        DWORD GSCookieXOROffset;
        DWORD EHCookieOffset;
        DWORD EHCookieXOROffset;
        _EH4_SCOPETABLE_RECORD ScopeRecord[1];
    };

    struct _EH4_SCOPETABLE_RECORD {
        DWORD EnclosingLevel;
        long (*FilterFunc)();
            union {
            void (*HandlerAddress)();
            void (*FinallyFunc)();
        };
    };
```

The code to generate the EHCookie is added in `X86WinEHState.cpp`.
Which is adding these instructions when using SEH4.

```
Lfunc_begin0:
# BB#0:                                 # %entry
	pushl	%ebp
	movl	%esp, %ebp
	pushl	%ebx
	pushl	%edi
	pushl	%esi
	subl	$28, %esp
	movl	%ebp, %eax                <<-- Loading FramePtr
	movl	%esp, -36(%ebp)
	movl	$-2, -16(%ebp)
	movl	$L__ehtable$use_except_handler4_ssp, %ecx
	xorl	___security_cookie, %ecx
	movl	%ecx, -20(%ebp)
	xorl	___security_cookie, %eax  <<-- XOR FramePtr and Cookie
	movl	%eax, -40(%ebp)           <<-- Storing EHGuard
	leal	-28(%ebp), %eax
	movl	$__except_handler4, -24(%ebp)
	movl	%fs:0, %ecx
	movl	%ecx, -28(%ebp)
	movl	%eax, %fs:0
	movl	$0, -16(%ebp)
	calll	_may_throw_or_crash
LBB1_1:                                 # %cont
	movl	-28(%ebp), %eax
	movl	%eax, %fs:0
	addl	$28, %esp
	popl	%esi
	popl	%edi
	popl	%ebx
	popl	%ebp
	retl

```

And the corresponding offset is computed:
```
Luse_except_handler4_ssp$parent_frame_offset = -36
	.p2align	2
L__ehtable$use_except_handler4_ssp:
	.long	-2                      # GSCookieOffset
	.long	0                       # GSCookieXOROffset
	.long	-40                     # EHCookieOffset    <<----
	.long	0                       # EHCookieXOROffset
	.long	-2                      # ToState
	.long	_catchall_filt          # FilterFunction
	.long	LBB1_2                  # ExceptionHandler

```

Clang is not yet producing function using SEH4, but it's a work in progress.
This patch is a step toward having a valid implementation of SEH4.
Unfortunately, it is not yet fully working. The EH registration block is not
allocated at the right offset on the stack.

Summary:
Code generation for Cortex-A72/Cortex-A73 was accidentally changed
by r271555, which was a NFCI. The isCortexA57() predicate was not true
for Cortex-A72/Cortex-A73 before r271555 (since it was checking the CPU
string). Because Cortex-A72/Cortex-A73 inherit all features from Cortex-A57,
all decisions previously guarded by isCortexA57() are now taken.

This change restores the behaviour before r271555 by adding separate
ProcA72/ProcA73, which have the required features to preserve code
generation.

Summary:
We have switched to using features for all heuristics, but
the tests for these are still using -mcpu, which means we
are not directly testing the features.

This converts at least some of the existing regression tests
to use the new features.

This still leaves the following features untested:

merge-narrow-ld
predictable-select-expensive
alternate-sextload-cvt-f32-pattern
disable-latency-sched-heuristic

This patch adds the __sanitizer_start_switch_fiber and
__sanitizer_finish_switch_fiber methods inspired from what can be found here
https://github.com/facebook/folly/commit/2ea64dd24946cbc9f3f4ac3f6c6b98a486c56e73 .

These methods are needed when the compiled software needs to implement
coroutines, fibers or the like. Without a way to annotate them, when the program
jumps to a stack that is not the thread stack, __asan_handle_no_return shows a
warning about that, and the fake stack mechanism may free fake frames that are
still in use.

Summary:
canCombineSinCosLibcall() would previously combine sin+cos into sincos for
GNUX32/GNUEABI/GNUEABIHF regardless of whether UnsafeFPMath were set or not.
However, GNU would only combine them for UnsafeFPMath because sincos does not
set errno like sin and cos do. It seems likely that this is an oversight.
