Paired Nested Macroses Support

[Dmytro Tarasiuk]

Good day!

Writing paired nested macros is not possible in the gas macro assembler.
For example, BEGIN/WHILE macros for loops, etc.  This is important to me
for writing portable pseudocode between different architectures that
supports gas.  I have implemented this extension since version 2.35.1
binutils and have to manually migrate it with each new stable release.
There are very few changes.  How can they be included into main code? Is it
really?

Regards.
