Subject: [ARM, Asm] Remove dead code causing MSan failure.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0c78a7a9de25f38724f56ed708474b30f4856f8d;p=llvm

[ARM, Asm] Remove dead code causing MSan failure.

r314779 caused ErrorInfo to be red uninitialised, but also made this code dead,
so it can just be removed.
