Ian Rogers cb94a02e74 perf metric: Restructure struct expr_parse_ctx.
A later change to parsing the ids out (in expr__find_other) will
potentially drop hashmaps and so it is more convenient to move
expr_parse_ctx to have a hashmap pointer rather than a struct value.

As this pointer must be freed, rather than just going out of scope, add
expr__ctx_new and expr__ctx_free to manage expr_parse_ctx memory.
Adjust use of struct expr_parse_ctx accordingly.
