When we know the bounds of the array, print any embedded nuls instead of treating them as terminators. An exception to this rule is made for the nul character at the very end of the string. We don't print that, as otherwise 99% of the strings would end in \0. This way the strings usually come out the same as how the user typed it into the compiler (char foo[] = "with\0nuls"). It also matches how they come out in gdb. This resolves a FIXME left from D111399, and leaves another FIXME for dealing with nul characters in "escape-non-printables=false" mode. In this mode the characters cause the entire summary string to be terminated prematurely. Differential Revision: https://reviews.llvm.org/D111634
