[linux-port] Use standard int literal suffixes (#1276)

Replaces -i64 suffixes with -LL which are said to be equivalent by
MSDN. Both should result in 64 bit behavior.

Additionally, I dropped a superfluous repetition of the class name
on the CheckVectorConditional method of HLSLExternalSource. By all
rights, it should be its own change, but it gets lonely so it came
along for the ride. The repeated class name made some compilers
unhappy and losing it doesn't bother anyone.
