[ubsan-minimal] update comments in CMakeLists.txt Summary: Prepend minimal when UBsan is mentioned and delete a dead comment Patch by Igor Sugak Reviewers: eugenis, pcc Reviewed By: eugenis Subscribers: mgorny, llvm-commits, #sanitizers Differential Revision: https://reviews.llvm.org/D53826 llvm-svn: 345557

# Build for the minimal undefined behavior sanitizer runtime support library.
Minimal runtime for UBSan. Summary: An implementation of ubsan runtime library suitable for use in production. Minimal attack surface. * No stack traces. * Definitely no C++ demangling. * No UBSAN_OPTIONS=log_file=/path (very suid-unfriendly). And no UBSAN_OPTIONS in general. * as simple as possible Minimal CPU and RAM overhead. * Source locations unnecessary in the presence of (split) debug info. * Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at. * above two items save 3% binary size. When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.
