RFR: 8352946: SEGV_BND signal code of SIGSEGV missing from our signal-code table

[Matthias Baesken]

On Linux we had recently a crash looking like this


siginfo_t @ 0x00007fff2723dc98:
  Signal: 11 (SIGSEGV)
  Signal Code: 3 (unknown signal code)
  Address of faulting memory reference: 0x007fff8c31629838


Seems signal code 3 is
`#define SEGV_BNDERR 3 /* failed address bound checks */`

so we should add this to our signal code table; on AIX I cannot find this code so it might be Linux-only.
Even on Linux the define is not always available in the system headers so we better add a define .
