c9db320410 xtensa: fix semihosting arguments potentially begin optimized out
The compiler was not informed that the assembly block should be
treated as a memory barrier and could optimize out the initialization
of local arrays which could be used as semihosting arguments.
This resulted in garbage values being passed as semihosting call
arguments.

Additionally this commit changes the approach for placing values into
specific register. Instead of clobbers, local register variables are
used. This results in simpler generated code, since the compiler is
able to place values directly into the registers used for semihosting
arguments, avoiding additional moves.

https_server: Add config option to min. cert. auth mode
- Added a config option to set the minimum Certificate Verification
  mode to Optional
- When this option is enabled, the peer (the client) certificate
  is checked by the server, however the handshake continues even if
  verification failed.
- By default, the peer certificate is not checked and ignored by the server.
