AArch64: Make every option in options.def one line

Due to config.gcc all the options need to be on one line because of the grep
lines which would select only the first line of the option.

This causes it not to select the right bits on options that are spread over
multiple lines when the --with-arch configure option is used.  The issue happens
silently and you just get a compiler with an incorrect set of default flags.

This solution just collapses everything back to one line as they were in GCC7.
Unfortunately this does make some lines quite long.

I do have an alternate patch which used the pre-processors to first flatten the
file in config.gcc.  I will send that one out for GCC 10.

AArch64: Have empty HWCAPs string ignored during native feature detection

This patch makes the feature detection code for AArch64 GCC not add features
automatically when the feature had no hwcaps string to match against.

This means that -mcpu=native no longer adds feature flags such as +profile.
The behavior wasn't noticed before because at the time +profile was added a bug
was preventing any feature bits from being added by native detections.

The loop has also been changed as Jakub specified in order to avoid a memory
leak that was present in the existing code and to be slightly more efficient.

    When using PPC64 ELF ABI v1 a function address is not a PC, but is the
    address of a function descriptor.  The first field in the function

    in both runtime and runtime/pprof.

    This patch fixes funcPC by recording, in the internal/cpu package,
    whether function descriptors are being used.  We have to check for

PR c++/86969 - ICE with constexpr if and recursive generic lambdas.

Here, the problem was that extract_local_specs wasn't seeing that we use
'self' inside the lambda in the else of the inner constexpr if, because we
don't walk into lambda bodies and we didn't capture it in the lambda because
'self' is still dependent.  Marek recently changed process_outer_var_ref to
do more implicit capture in templates; this example shows that we should
always capture non-packs, so that we can continue to not walk into lambda
bodies.  We do walk into lambda bodies for pack expansions, so we can delay
deciding whether we're capturing a single element or the entire pack.

Immediately capturing a VLA means we need to create a dependent VLA capture
type, and not in the context of the lambda op(), since trying to look up the
instantiation of the op() while we're substituting into the capture list
would crash.  So I force TYPE_CONTEXT and the binding level out to the
enclosing function before pushtag, avoid adding a TAG_DEFN, and instead
force the type to be complete in tsubst_lambda_expr.

* semantics.c (process_outer_var_ref): Do capture dependent vars.
* class.c (finish_struct): Only add TAG_DEFN if T is in
