zig0 takes too much RAM to build zig1.o #6485
Description
Hello,
Due to the recent changes in the internals of the zig compiler, I'm no longer able to build the compiler anymore.
The build fails at 99% where the self hosted component zig1.o is being built
Here's a small snippet

I have 4GB of ram on my system and I'd assume it's enough ram to build the zig compiler as I was able to do that before the restructuring. After the commit 0.6.0+f8b3543ca I am unable to build the compiler due to enormous amount of ram that is required.
I'd like to be able to compile the build on my system because it's one the features of the compiler that I liked. Unlike other languages.
