35c19de696 compiler: make heap expression's write barrier conditional 
Heap_expression::do_get_backend emits an unconditional write
    barrier if the type has pointers and it is not a stack allocation.
    This CL changes it to use a write barrier for the assignment only
    when write barriers are enabled. While here, also change it to
    call gcWriteBarrier instead of typedmemmove for pointer-shaped
    types.
    
    For this to work, Function::build needs to be adjusted so that
    Heap_expression::do_get_backend is called when there is a parent
    block.

fc917b4265 compiler: permit inlining functions with labels and goto statements 
This permits inlining functions with for loops and some switches, as
    they are lowered to if and goto statements before exporting them.
    
    This by itself only adds three new inlinable functions in the standard
    library: sort.Search, context.(*emptyCtx).String, and
    cmd/go/internal/work.(*Builder).disableBuildID.

d480455f2d compiler: use gcWriteBarrier for pointer-shaped struct/array 
If a struct/array is pointer-shaped (i.e. having a single field
    that is pointer-shaped), we can use gcWriteBarrier instead of
    typedmemmove for the write barrier.

c2f879e1fe compiler: make escape analysis work with imported inlineable functions 
The escape analysis was written before we import inlineable
    function bodies, and in some places it skipped functions that are
    not in the local package. Now that there are imported function
    bodies, make the escape analysis work with them.
    
    Note that it is necessary for the escape analysis to run on
    imported function bodies, even if they are already tagged. The
    tags only have the information of the parameters (receiver,
    results), but not the internal nodes, e.g. local variables. We
    still need to do the analysis to get all the information. (In the
    future maybe we could export/import escape info for internal
    nodes also, then we don't need to redo the analysis.)
    
    Also add assertions to ensure that if we analyze the same
    function in multiple places, they'd better agree with each other.

39d1184ba8 PR other/90695 reduce testcase to remove library dependency 
This reproduces the original ICE fixed by r178857 (tested at r178852 and
r178860), without depending on a libstdc++ header that keeps changing.

The number of errors differs between C++14 and C++17 modes, so the fixed
test uses dg-excess-errors to match any number of them. The precise
errors aren't what's being tested for here anyway, the point of the test
is to verify the ICE in PR 50391 is fixed.
