Handle missing Solaris auxv entries
Currently, three tests FAIL on Solaris 11.4+ (amd64-pc-solaris2.11 and
sparcv9-sun-solaris2.11):

FAIL: gdb.base/auxv.exp: info auxv on gcore-created dump
The following patch fixes this by introducing the missing AT_SUN_*
values from Solaris 11.4+ <sys/auxv.h>. This lets the live and
gcore-created dump tests PASS.
I don't know yet what's the reason for those weird 'Unrecognized tag
value' warnings with native core dumps is; elfdump -n certainly doesn't
show them. However, native core dumps still need quite some work
(mostly in bfd) in this and other areas.
Tested on amd64-pc-solaris2.11.
gdb:
* auxv.c (default_print_auxv_entry): Reflect AT_SUN_CAP_HW1
renaming.
Handle AT_SUN_EMULATOR, AT_SUN_BRANDNAME, AT_SUN_BRAND_AUX1,
AT_SUN_BRAND_AUX2, AT_SUN_BRAND_AUX3, AT_SUN_CAP_HW2.
include:
* elf/common.h (AT_SUN_HWCAP): Rename to ...
(AT_SUN_CAP_HW1): ... this. Retain old name for backward
compatibility.
(AT_SUN_EMULATOR, AT_SUN_BRANDNAME, AT_SUN_BRAND_AUX1)
(AT_SUN_BRAND_AUX2, AT_SUN_BRAND_AUX3, AT_SUN_CAP_HW2): Define.
