"delayed_cr" is just "cr_logical" with the second source operand not
equal to the destination operand.  This patch changes it to be
expressed as type "cr_logical", with a new boolean attribute
"cr_logical_3op" added.  This simplifies code.

    Reclaim the memory of escape analysis Nodes before kicking off
    the backend, as they are not needed in get_backend.

    Local variables captured by the deferred closure need to be live
    until the function finishes, especially when the deferred
    function runs. In Function::build, for function that has a defer,
    we wrap the function body in a try block. So the backend sees
    the local variables only live in the try block, without knowing
    that they are needed also in the finally block where we invoke
    the deferred function. Fix this by creating top-level
    declarations for non-escaping address-taken locals when there
    is a defer.
    
    An example of miscompilation without this CL:
    
    func F(fn func()) {
            didPanic := true
            defer func() {
                    println(didPanic)
            }()
            fn()
            didPanic = false
    }
    
    With escape analysis turned on, at optimization level -O1 or -O2,
    the store "didPanic = false" is elided by the backend's
    optimizer, presumably because it thinks "didPanic" is not live
    after the store, so the store is useless.

From-SVN: r256698

In this wrong-code bug we combine a VSUB.I8 and a VABS.S8
into a VABD.S8 instruction . This combination is not valid
for integer operands because in the VABD instruction the semantics
are that the difference is computed in notionally infinite precision
and the absolute difference is computed on that, whereas for a
VSUB.I8 + VABS.S8 sequence the VSUB operation will perform any
wrapping that's needed for the 8-bit signed type before the VABS
gets its hands on it.

This leads to the wrong-code in the PR where the expected
sequence from the intrinsics:
VSUB + VABS of two vectors {-100, -100, -100...}, {100, 100, 100...}
gives a result of {56, 56, 56...} (-100 - 100)

but GCC optimises it into a single
VABD of {-100, -100, -100...}, {100, 100, 100...}
which produces a result of {200, 200, 200...}

The transformation is still valid for floating-point operands,
which is why it was added in the first place I believe (r178817)
but this patch disables it for integer operands.
The HFmode variants though only exist for TARGET_NEON_FP16INST, so
this patch adds the appropriate guards to the new mode iterator

Add -mfunction-return= option to convert function return to call and
return thunks.  The default is 'keep', which keeps function return
unmodified.  'thunk' converts function return to call and return thunk.
'thunk-inline' converts function return to inlined call and return thunk.
'thunk-extern' converts function return to external call and return
thunk provided in a separate object file.  You can control this behavior
for a specific function by using the function attribute function_return.

Function return thunk is the same as memory thunk for -mindirect-branch=
where the return address is at the top of the stack:

__x86_return_thunk:
	call L2
L1:
	pause
	lfence
	jmp L1
L2:
	lea 8(%rsp), %rsp|lea 4(%esp), %esp
	ret

and function return becomes

	jmp __x86_return_thunk

-mindirect-branch= tests are updated with -mfunction-return=keep to
avoid false test failures when -mfunction-return=thunk is added to
RUNTESTFLAGS for "make check".
