Summary

This patch eliminates the following warning

lib/IR/AsmWriter.cpp:1128:57: warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]

(StrVal[1] >= '0' && StrVal[1] <= '9')) &&

LG. No need to submit review for fixing trival warnings like this.

Ok, Thank you!

The reason I posted this for a review is that when i've got a committer access, e-mail said: "commit after approval access granted".

I thought that I should post all patches for the review.
