`false` becomes `!1` in error messages

[jakeg]

Run this code:

let a = {}
a.b.c = { d: false }

eg with bun -e "let a = {}; a.b.c = { d: false }"

Gives this error:

TypeError: undefined is not an object (evaluating 'a.b.c = { d: !1 }')

... I would expect the error to say evaluating 'a.b.c = { d: false }' not evaluating 'a.b.c = { d: !1 }'

For context the !1 is the minified form of false, so this means that it's proabibly a sourcemap issue
