compiler: add escape analysis debug hash
Add a flag -fgo-debug-escape-hash for debugging escape analysis.
It takes a binary string, optionally led by a "-", as argument.
When specified, the escape analysis runs only on functions whose
name is hashed to a value with matching suffix. The "-" sign
negates the match, i.e. the analysis runs only on functions with
non-matching hash.
Reviewed-on: https://go-review.googlesource.com/83878
* lang.opt (fgo-debug-escape-hash): New option.
* go-c.h (struct go_create_gogo_args): Add debug_escape_hash
field.
* go-lang.c (go_langhook_init): Set debug_escape_hash field.
* gccgo.texi (Invoking gccgo): Document -fgo-debug-escape-hash.
