Fix the following build failure generated with command
$ make CC=clang HOSTCC=clang -C tools/ perf:
util/intel-pt.c:1802:24: error: field 'br_stack' with variable sized type
'struct branch_stack' not at the end of a struct or class is a GNU extension
[-Werror,-Wgnu-variable-sized-type-not-at-end]
struct branch_stack br_stack;
^
1 error generated.
Fix this by reordering the members of struct br.
Clang version 11.0.0 was used.
