[committed][gdb/testsuite] Fix gdb.ada/operator_bp.exp breakpoint location FAILs

[Tom de Vries <tdevries@suse.de>]

Hi,

When running test-case gdb.ada/operator_bp.exp with gcc-10, I run into:
...
FAIL: gdb.ada/operator_bp.exp: break "+"
FAIL: gdb.ada/operator_bp.exp: break "-"
FAIL: gdb.ada/operator_bp.exp: break "<"
FAIL: gdb.ada/operator_bp.exp: break "<="
FAIL: gdb.ada/operator_bp.exp: break ">"
FAIL: gdb.ada/operator_bp.exp: break ">="
FAIL: gdb.ada/operator_bp.exp: break "="
FAIL: gdb.ada/operator_bp.exp: break "and"
FAIL: gdb.ada/operator_bp.exp: break "or"
FAIL: gdb.ada/operator_bp.exp: break "xor"
FAIL: gdb.ada/operator_bp.exp: break "not"
...

The first FAIL is because two breakpoint locations are expected, but there are
more than 2:
...
(gdb) break "+"
Breakpoint 2 at 0x402c3c: "+". (6 locations)
(gdb) info break
Num     Type           Disp Enb Address            What
2       breakpoint     keep y   <MULTIPLE>
2.1                         y   0x0000000000402c3c in ops."+"
                                                   at operator_bp/ops.adb:25
2.2                         y   0x0000000000402e5b in ops."+"
                                                   at operator_bp/ops.adb:119
2.3                         y   0x0000000000414207 in
  system.storage_elements."+" at s-stoele.adb:82
2.4                         y   0x0000000000414404 in
  system.storage_elements."+" at s-stoele.adb:87
2.5                         y   0x0000000000414413 in
  system.storage_elements."+" at s-stoele.adb:87
2.6                         y   0x0000000000414430 in
  system.storage_elements."+" at s-stoele.adb:81
...

This can be traced back to a extra debug info in the executable:
...
$ readelf -w ops_test | grep system__storage_elements__Oadd
    <28104>   DW_AT_name        : system__storage_elements__Oadd__2
    <2812e>   DW_AT_name        : system__storage_elements__Oadd
...

Fix the FAILs by allowing more than the required amount of breakpoint
locations.

Tested on x86_64-linux.

Committed to trunk.

Thanks,
