Fix a load of aliasing build errors:

make[1]: *** [tilegx-tdep.o] Error 1
from an attempt to cast a `long long' pointer to an `int64_t' pointer,
which may not necessarily be compatible types. Use the `long long' type
for the auxiliary variable then as this is the type of the structure
member referred.

* tilegx-tdep.c (tilegx_analyze_prologue): Use the `long long'
type for `operands'.
