Subject: [PATCH 00/10] objtool: Honey, I shrunk the instruction

Hi,

Boris complained he could no longer build allyesconfig on his 32G desktop
machine without having OOM terminate either objtool or chrome.

After talking about these patches on IRC, Nathan mentioned the linux-clang CI
was also having trouble of recent, and these patches appear to make it happy
again.

In total these patches shrink an allyesconfig run by about 6G:
