  [lldb] [Process/elf-core] Fix reading FPRs from FreeBSD/i386 cores

The FreeBSD coredumps from i386 systems contain only FSAVE-style
NT_FPREGSET.  Since we do not really support reading that kind of data
anymore, just use NT_X86_XSTATE to get FXSAVE-style data when available.

  -----------
  [Process/elf-core] Read PID from FreeBSD prpsinfo

Add a function to read NT_PRPSINFO note from FreeBSD core dumps.  This
is necessary to get the process ID (NT_PRSTATUS has only thread ID).
Move the lp64 check from NT_PRSTATUS parsing to the parseFreeBSDNotes()
to avoid repeating it.
