This reverts commit b23c47ae6d because
it broke CI.

b23c47ae6d [ELF] Garbage-collect C identifier sections 
If a section name is valid as a C identifier (i.e. it doesn't start
with '.' and doesn't contain any punctuators), the linker automatically
creates new symbols by prepending `__start_` and `__stop_` to the
section name.

Previously, we conservatively keep such C identifier sections during
garbage collection. However, since `__start_` and `__stop_` symbols
are hidden symbols, if we do not have `__start_foo` or `__stop_foo`,
we can safely discard section `foo`.

536e0e7dca [elf] Align .symtab's ELF attributes with .dynsym's. 
Notably, we previously wrote symbols that have been demoted into STB_LOCAL
as STB_GLOBAL. Fix this by using a logic shared with dynsym to determine
the output attributes.

Also reorder the symbols since the LOCAL ones need to come first.

Found in Mesa test suite.

764d7575f7 [ELF] Define __dso_handle 
`cxa_finalize` takes `__dso_handle` to uniquify identify an ELF module
in memory. Its actual location doesn't matter but needs to be different
for each ELF module.

31d2a902e5 Fix run.sh failure on musl 
The command "mold -run foo.ld" can fail when foo.ld is an empty file.
The musl execvp() call fails with "Exec format error" when the script
to be executed is empty. The fix is to create foo.ld with a valid
Unix shebang.

Implement `--(no-)allow-shlib-undefined. 
This also fixes the `note-property` test which was hanging on my
machine. Turns out `$CC` was stuck waiting to read from `stdin`,
and as such I decided to write something into it.
