i386: Update INCOMING_FRAME_SP_OFFSET for exception handler

Since there is an extra error code passed to the exception handler,
INCOMING_FRAME_SP_OFFSET is return address plus error code for the
exception handler.  This patch updates INCOMING_FRAME_SP_OFFSET to
the correct value for the exception handler.

This patch exposed a bug in DWARF stack frame CFI generation, which
assumes that INCOMING_FRAME_SP_OFFSET is the same for all functions:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81570

It sets and caches the incoming stack frame offset with the same
INCOMING_FRAME_SP_OFFSET for all functions.  When there are both
exception handler and normal function in the same input, the wrong
incoming stack frame offset is used for exception handler or normal
function, which leads to

compiler: add backend type conversion

    Tweak Interface_field_reference_expression::do_get_backend to apply an
    additional backend type conversion to the returned result.  This is
    needed due to the fact that the top level type of the expression is a
    function descriptor, however the value being manufactured is a pointer
    to <thunk-descriptor, value> struct.

compiler: track placeholder pointer types for conversion

    We recently started walking through the hash table of pointer types to
    finalize them.  Unfortunately it is possible to create a new pointer
    type while finalizing an existing one (test case: test/fixedbugs/issue5291)
    and that breaks the iteration.  So, instead, keep a list of
    placeholder pointer types, and iterate through them while permitting
    the list to be extended as we go.

compiler: use a single temporary for calls with multiple results

    For calls that return multiple results we used to create a temporary
    of struct type to hold the results, and also create a separate
    temporary for each result.  Then the call expression would copy each
    result out of the struct to the temporary, and Call_result_expression
    would refer to the desired temporary.

    Simplify this to just use a single temporary of struct type, and
    change Call_result_expression to fetch a field of the struct.

    This may reduce some incorrect tree sharing in the backend code.

[PATCH][AArch64] Fix missing optimization for CMP+AND

During combine GCC tries to merge CMP (with zero) and AND into a TST. However,
in cases where an ANDS operand is not compatible, this was being missed. Adding
a define_split where this operand was moved to a register seems to help out.
