internal/cpu, runtime, runtime/pprof: handle function descriptors
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
descriptor is the actual PC (see
http://refspecs.linuxfoundation.org/ELF/ppc64/PPC-elf64abi.html#FUNC-DES).
The libbacktrace library knows about this, and libgo uses actual PC
values consistently except for the helper function funcPC that appears
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
function descriptors using a C compiler check, because GCC can be
configured using --with-abi to select the ELF ABI to use.

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.

This patch checks for the local stylesheet directory first, and doesn't

AArch64: Fix command line options canonicalization version #2. (PR target/88530)
Commandline options on AArch64 don't get canonicalized into the smallest
possible set before output to the assembler. This means that overlapping feature
sets are emitted with superfluous parts.
Normally this isn't an issue, but in the case of crypto we have retro-actively
split it into aes and sha2. We need to emit only +crypto to the assembler
so old assemblers continue to work.
Because of how -mcpu=native and -march=native work they end up enabling all
feature bits. Instead we need to get the smallest possible set, which would also
fix the problem with older the assemblers and the retro-active split.
The function that handles this is called quite often. It is called for any
push/pop options or attribute that changes arch, cpu etc. In order to not make
this search for the smallest set too expensive we sort the options based on the
number of features (bits) they enable. This allows us to process the list
linearly instead of quadratically (Once we have enabled a feature, we know that
anything else that enables it can be ignored. By sorting we'll get the biggest
groups first and thus the smallest combination of commandline flags).
The Option handling structures have been extended to have a boolean to indicate
whether the option is synthetic, with that I mean if the option flag itself
enables a new feature.
e.g. +crypto isn't an actual feature, it just enables other features, but others
like +rdma enable multiple dependent features but is itself also a feature.
There are two ways to solve this.
1) Either have the options that are feature bits also turn themselves on, e.g.
change rdma to turn on FP, SIMD and RDMA as dependency bits.
2) Make a distinction between these two different type of features and have the
framework handle it correctly.
Even though it's more code I went for the second approach, as it's the one
that'll be less fragile (people can't forget it) and gives the least surprises.
Effectively this patch changes the following:
The values before the => are the old compiler and after the => the new code.
-march=armv8.2-a+crypto+sha2 => -march=armv8.2-a+crypto
-march=armv8.2-a+sha2+aes => -march=armv8.2-a+crypto
The remaining behaviors stay the same.
