  PR symtab/29105 concerns an over-eager CU expansion bug with the new
DWARF reader.  This short series fixes the bug.

The first two patches are tiny refactorings to make the final patch
more understandable.

I don't know how to write a good test for this.  In order to try it,
what I had to do on my machine was to install the glibc debuginfo,
disable the use of the gdb index by hacking dwarf2_initialize_objfile
(Fedora uses .gdb_index in the system debuginfo), and finally run the
sizeof.exp test and try it out by hand, with "set debug symtab-create
1".

Regression tested on x86-64 Fedora 34.  Let me know what you think.
