LTTng 0.91 optimizes data copy primitives

[Mathieu Desnoyers]

Hi,

I just released LTTng 0.91 in which I've had a 20% performance increase
when tracing in flight recorder mode when compiling a kernel by creating
an inlined optimized (memcpy-less for 1, 2, 4, and 8 bytes) fast path
for the low-level data copy primitive.

Here is the commit :
