gdb: Fix std::{min, max}-related build breakage on 32-bit hosts
Building on a 32-bit host fails currently with errors like:
.../src/gdb/exec.c: In function ‘target_xfer_status section_table_read_available_memory(gdb_byte*, ULONGEST, ULONGEST, ULONGEST*)’:
.../src/gdb/exec.c:801:54: error: no matching function for call to ‘min(ULONGEST, long unsigned int)’
end = std::min (offset + len, r->start + r->length);

The problem is that the std::min/std::max function templates use the
same type for both parameters. When the argument types are different,
the compiler can't automatically deduce which template specialization
to pick from the arguments' types.
Fix that by specifying the specialization we want explicitly.
gdb/ChangeLog:
2016-09-18 Pedro Alves <palves@redhat.com>
* breakpoint.c (hardware_watchpoint_inserted_in_range): Explicitly
specify the std:min/std::max specialization.
* exec.c (section_table_read_available_memory): Likewise.
* remote.c (remote_read_qxfer): Likewise.
* target.c (simple_verify_memory): Likewise.
