Do not create invalid pointers in C code of string functions.
Some of the x86 string functions create pointers based on input strings that may be outside of the input strings. When this happens in C code, the compiler can potentially detect this, leading to warnings in application code when those string functions are inlined. Perform those operations in the assembly code instead of the C code to fix this.
