Javascript library doesn't compile under gcc7

Spidermonkey doesn't compile under gcc7. I don't seem to have access to that module, so here's a diff for the fix:

diff --git a/js/src/nanojit/NativeX64.cpp b/js/src/nanojit/NativeX64.cpp

+    static const AVMPLUS_ALIGN16(uint64_t) negateMask[] = {0x8000000000000000LL,0};

     void Assembler::asm_fneg(LIns *ins) {
         Register rr, ra;

The problem is that the constant 0x8000000000000000LL is technically outside the range for an int64_t, although it's got the right number of bits, and gcc7 refuses to build it. Changing the type to uint64_t fixes the build.

Thanks for the fix Kevin. Submitted to the mozilla submodule and the issue can be closed.
