some bugfix

[zqxiaojin]

fix basename error
fix get die name
fix cplus name demangle
fix dwarf file sholud also search symtab
fix the CI error

[zqxiaojin]

for "fix get die name"， I try to search ref die to get the right name of dwarf symbol.

[zqxiaojin]

use "cplus_demangle_v3(sym, 1 << 0)" instead of "cplus_demangle(sym, 0)" to make some cplus symbol which have namespace to show correct with function params.

After you lookup a address at dwarf file and fail to get the symbol, you should try to lookup the address also at symtable . Because the executable file may link to a static library which has been strip debug info.

Thanks! In general I think the changes look good, but a few comments before I do a more thorough review:

1. Can you merge the fixes and style changes into the appropriate commits
2. having 1-4 listed in a commit message implies that there should really be four separate commits, can you split them up?
3. it's not entirely clear what all of these bullet points are fixing, so when you split them up can you add a comment explaining the purpose of the change?
4. Can you show some tests to make sure nothing broken? I know, we should have a better automated suite, but we don't yet :(
