    • Make lto.exp work with Tcl 8.4 · d66f0329 
      "dict" was added in Tcl 8.5, but until a couple of weeks ago the
testsuite had worked with 8.4.

This patch uses arrays instead, like we do for the caching in
target-supports.exp.  It is a bit uglier than using dicts was,
but hopefully not too bad...

    • compiler: rollback "avoid negative zero in float constants" · 60d25b80 
          
    It uses functions that are not available in MPFR 2.4.2, which is the
    current version supported by GCC.
    
    Original change description:
    
        compiler: avoid negative zero in float constants
    
        Check for negative numbers with very small magnitudes that will round
        to negative zero, and force them to positive zero instead.
    
        This implements the spec clarification in https://golang.org/cl/14727.
        The test is in https://golang.org/cl/91895.

    • [AArch64] Remove SVE XFAILs · ba261579 
      These tests started passing after r257293, which had the side-effect
of renumbering the SSA names and leaving the COND_EXPRs in their
natural order.

This does show a deeper underlying issue that code generation is too
sensitive to internal things like SSA_NAME versions, but it no longer
affects these particular tests (for now).

    • compiler: update iota handling, fix using iota in array length · 5dfb4d0f 
          
    CL 71750 changed the definition of how iota works.  This patch updates
    gccgo for the new definition.
    
    We've been mishandling iota appearing in a type that appears in a
    const expression, as in `c = len([iota]int{})`.  Correct that by copying
    type expressions when we copy an expression.  For simplicity only copy
    when it can change the size of a type, as that is the only case where
    iota in a type can affect the value of a constant (I think).  This is
    still a bunch of changes, but almost all boilerplate.

    • compiler: in range, evaluate array if it has receives or calls · 964c809f 
          
    The last change was incomplete, in that it did not evaluate the array
    argument in some cases where it had to be evaluated.  This reuses the
    existing code for checking whether len/cap is constant.
    
    Also clean up the use of _ as the second variable in a for/range,
    which was previously inconsistent depending on whether the statement
    used = or :=.
