gdb: use decltype instead of typeof in dwarf2/read.c
When building with -std=c++11, I get:
CXX dwarf2/read.o
/home/smarchi/src/binutils-gdb/gdb/dwarf2/read.c: In function ‘void dwarf2_build_psymtabs_hard(dwarf2_per_objfile*)’:
/home/smarchi/src/binutils-gdb/gdb/dwarf2/read.c:7130:23: error: expected type-specifier before ‘typeof’
7130 | using iter_type = typeof (per_bfd->all_comp_units.begin ());
| ^~~~~~
This is because typeof is a GNU extension. Use C++'s decltype keyword
instead.
