Replaces //go:linkname by assembly functions for syscall
functions on aix/ppc64.
Since the new runtime internal ABI, this was triggering an error if
syscall.Syscall6 was called by others packages like x/sys/unix.
This commit should remove every future occurences of this problem.

Instead of testing len(slice)+numNewElements > cap(slice) use
uint(len(slice)+numNewElements) > uint(cap(slice)) to test
if a slice needs to be grown in an append operation.
This prevents a possible overflow when len(slice) is near the maximum
int value and the addition of a constant number of new elements
makes it overflow and wrap around to a negative number which is
smaller than the capacity of the slice.
Appending a slice to a slice with append(s1, s2...) already used
a uint comparison to test slice capacity and therefore was not
vulnerable to the same overflow issue.

That number grows quadratically with the number of intermediate
certificates in certain pathological cases (for example if they all have
the same Subject) leading to a CPU DoS. Set a fixed budget that should
fit all real world chains, given we only look at intermediates provided
by the peer.
The algorithm can be improved, but that's left for follow-up CLs:
* the cache logic should be reviewed for correctness, as it seems to
override the entire chain with the cached one
* the equality check should compare Subject and public key, not the
whole certificate
* certificates with the right SKID but the wrong Subject should not
be considered, and in particular should not take priority over
certificates with the right Subject

To fix#5043, we added logic to allow balanced pairs of parenthesis
so that we could match URLs like:
http://example.com/some_resource(foo)
Howewer, such logic breaks when parsing something like the following:
art by [https://example.com/person][Person Name]].
such that the following is considered the link:
https://example.com/person][Person
Since the logic added in #5043 was just a heuristic, we adjust
the heuristic that in addition to requiring balanced pairs,
the first parenthesis must be an opening one.
For further robustness, we apply this heuristic to
parenthesis, braces, and brackets.

This change implements Payne-Hanek range reduction by Pi/4
to properly calculate trigonometric functions of huge arguments.
The implementation is based on:
"ARGUMENT REDUCTION FOR HUGE ARGUMENTS: Good to the Last Bit"
K. C. Ng et al, March 24, 1992
The major difference with the reference is that the simulated
multi-precision calculation of x*B is implemented using 64-bit
integer arithmetic rather than floating point to ease extraction
of the relevant bits of 4/Pi.
The assembly implementations for 386 were removed since the trigonometric
instructions only use a 66-bit representation of Pi internally for
reduction. It is not possible to use these instructions and maintain
accuracy without a prior accurate reduction in software as recommended
by Intel.

By combining the load+op, we may force the op to happen earlier in
the store chain. That might force the SymAddr operation earlier, and
in particular earlier than its corresponding VarDef. That leads to
an invalid schedule, so avoid that.
This is kind of a hack to work around the issue presented. I think
the underlying problem, that LEAQ is not directly ordered with respect
to its vardef, is the real problem. The benefit of this CL is that
it fixes the immediate issue, is small, and obviously won't break
anything. A real fix for this issue is much more invasive.
