Make the stack non-executable in GNAT tools

Due to PR67205, the deeply nested instantiations require trampolines,
which in turn requires an executable stack for the GNAT tools on
architectures such as x86_64.

xtensa: fix _Unwind_GetCFA

Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
higher than what was actually used by code at context->ra. This results
in invalid CFA value in signal frames and premature unwinding completion
in forced unwinding used by uClibc NPTL thread cancellation.

compiler: Flatten erroneous subtrees into errors.

    Between the lowering and flattening passes of the compiler, there are
    several passes that modify the lowered Go parse tree and as errors are
    discovered, several nodes transform into error nodes.  However, for a
    higher level node such as a construction expression, the erroneous
    nodes in the subtrees might not propagate their error.  The flatten
    phase for a node now looks for errors in the subtree and flattens the
    node into an error node if any are found.

    Fixes golang/go#11559, golang/go#11536, golang/go#11558.

xtensa: add -mauto-litpools option

With support from assembler this option allows compiling huge functions,
where single literal pool at the beginning of a function may not be
reachable by L32R instructions at its end.

Currently assembler --auto-litpools option cannot deal with literals
used from multiple locations separated by more than 256 KBytes of code.
Don't turn constants into literals, instead use MOVI instruction to load
them into registers and let the assembler turn them into literals as
necessary.
