bug#38486: try all options

[Matt Wette]

The behavior is that guild compile 38486-1.scm hangs

These optimization flags eliminate that behavior: the code compiles quickly:
 -O0
 -O1
 -Ono-simplify
 -Ono-contify
 -Ono-cse
 -Ono-specialize-numbers

These optimization flags are ineffective: the behavior remains:
 -Ono-partial-eval
 -Ono-eliminate-dead-code
 -Ono-prune-top-level-scopes
 -Ono-inline-constructors
 -Ono-specialize-primcalls
 -Ono-elide-values
 -Ono-prune-bailouts
 -Ono-peel-loops
 -Ono-type-fold
 -Ono-resolve-self-references
 -Ono-licm
 -Ono-rotate-loops
 -Ono-precolor-calls
