The existing Thread Local Storage (TLS) implementation for riscv64 uses
initial-exec (IE) mode, however a MOV of a TLS symbol currently loads the
thread pointer offset and not the actual address or memory location.
Rework TLS on riscv64 to generate the full instruction sequence needed to
load from or store to a TLS symbol. Additionally, provide support for both
initial-exec (IE) and local-exec (LE) TLS - in many cases we can use LE,
which is slightly more efficient and easier to support in the linker.

timers on Windows when available, to avoid this problem.
Note that the default sampling rate (100Hz) is already too high
for the Windows timer resolution (15.6ms), so this CL also improves
the default Windows sampling coverage.
Not adding regression tests, as they would be too flaky.

Extremely large RSA keys in certificate chains can cause a client/server
to expend significant CPU time verifying signatures. Limit this by
restricting the size of RSA keys transmitted during handshakes to <=
8192 bits.
Based on a survey of publicly trusted RSA keys, there are currently only
three certificates in circulation with keys larger than this, and all
three appear to be test certificates that are not actively deployed. It
is possible there are larger keys in use in private PKIs, but we target
the web PKI, so causing breakage here in the interests of increasing the
default safety of users of crypto/tls seems reasonable.
Thanks to Mateusz Poliwczak for reporting this issue.

Older s390x before z13 did not have support to carry out floating point operations i.e. they didn't have the support for vector instructions like VX/VL, etc.
Starting with Go1.19, z13 is the minimum hardware level for running Go on LoZ (s390x). The main cause of this issue was the refactoring of elliptic curve to internal/nistec. The new code structures made it difficult to dynamically switch implementations at runtime, so it became necessary (in order machines to continue to use the accelerated implementation) to require z13 as the minimum hardware.
Hence, Go programs, when run on unsupported hardware, should crash on startup instead of crashing out in crypto code.

Fixes#61629
This reduce the pressure on regalloc because then the loop only keep alive
one value (the iterator) instead of the iterator and the upper bound since
the comparison now acts against an immediate, often zero which can be skipped.
This optimize things like:
for i := 0; i < n; i++ {
Or a range over a slice where the index is not used:
for _, v := range someSlice {
Or the new range over int from #61405:
for range n {
It is hit in 975 unique places while doing ./make.bash.

The method AddFS can be used to add the contents of a fs.FS filesystem
to a zip archive.
This method walks the directory tree starting at the root of the filesystem
and adds each file to the archive.
