Support analyse const values (dwarf.QualType)

[Zxilly]

This can be helpful for program embed things with const string.

I need this. I have a package which have a const string with 55MB and the .rdata is largest in gsa result.
I find this big file by searching big files in my source code.

I added this feature request, but I don't really have any ideas on how to implement it. The main problem is that the Go compiler will only output const tokens for int values in the dwarf, string types are ignored.
