Attempting to run 64-bit moo with -m -j causes a segfault. This should be fixed.
This patch implements the JaegerFromTracer glue for x86_64, making most of the tests pass. The failing tests trip asserts within the tracer, reproduced below:

python trace-test/trace-test.py dbg64/js -o sunspider/check-crypto-aes.js
Assertion failure: !f->typeMap.matches(peer->typeMap), at ../jstracer.cpp:1589

python trace-test/trace-test.py dbg64/js -o basic/testNewObject.js
Assertion failure: LIR type error (start of writer pipeline): arg 1 of 'ui2uq' is 'immq' which has type int64 (expected int32): 0 (../nanojit/LIR.cpp:2834)
http://hg.mozilla.org/projects/jaegermonkey/rev/fc549b24a1af

Pushed despite nanojit failures. Dvander says he'll look into them.

Ah, a long-forgotten bug.

No longer reproduces on tip. Closing.
