    • [Darwin, fixincludes] Fix Darwin9/10 math.h issues. · 5a50aed3 
      Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers.  However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10.  This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__.  The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.

This fixes the tr1 testsuite fails seen on Darwin9 and 10.

	* inclhack.def: Replace the complex test using __STRICT_ANSI__ and
	__STDC_VERSION__ with a test using __DARWIN_NO_LONG_LONG.
	Ensure that the top level math.h uses <> to wrap included headers
	rather than "".
	* fixincl.x: Regenerated.
	* tests/base/architecture/ppc/math.h: Update test to include the
	__DARWIN_NO_LONG_LONG case.

    • compiler: omit write barrier for assignment to *(convert(&local)) · 28b9598b 
          
    Assignments to local variables don't need a write barrier. But
    currently the compiler inserts a write barrier if the LHS is a
    local variable with type converted, as *(convert(&local)). Let
    the compiler recognize this pattern and omit the write barrier.

    • compiler: open code string slice expressions · c9b236e5 
          
    Currently a string slice expression is implemented with a runtime
    call __go_string_slice. Change it to open code it, which is more
    efficient, and allows the backend to further optimize it.
    
    Also omit the write barrier for length-only update (i.e.
    s = s[:n]).
