As stated in the code, "The builtin package needs special treatment: its
symbols are lower case but we want to see them, always". Thus, cmd/doc
forces the -u flag if the package being queried is called "builtin".
However, this happens after having already parsed the package. This
CL forces the -u flag just after parsing the command arguments and
before parsing any package.
Fixes#49796.

Tools like objdump uses the pcln table to find the line number of
a given PC. For a PIE binary, at least in some cases such as on
macOS 12 with ld64-711, the table contains unrelocated address,
which does not match the address in the symbol table, causing the
lookup to fail.
In Go 1.18 the pcln table is essentually position independent,
except the start PC. Instead of reading the static content from
the table, use the PC of runtime.text from the symbol table.
While here, change the type of textStart to uint64. What matters
here is the word size of the target program, not the host, so it
shouldn't be uintptr.

When we have a typed nil, we already say so; thus it is sufficient
to use "nil" in all the other cases.
This is closer to (1.17) compiler behavior. In cases where the
1.17 compiler prints "untyped nil" (e.g., wrong uses of "copy"),
we already print a different message. We can do better in those
cases as well; will be addressed in a separate CL (see #49735).
