Failing test - bitwise.lua with YKD_SERIALISE_COMPILATION=1

[Pavel-Durov]

Issue

Error on running bitwise.lua test with serial compilation:

$ YKD_SERIALISE_COMPILATION=1 ../src/lua -e"_U=true" bitwise.lua

Fails with error:

Floating point instructions are not supported yet:   %618 = sitofp i32 %612 to double, !dbg !9498 x kimchi@kimchi-machine ~/git-repos/yklua-fork/tests yk-location-allocation/056cf6ae7cb3ebd59a7e0dc89df99c03f0e8d3d9

However, when running with non-serialised compilation it works:

$ try_repeat 1000 ../src/lua -e"_U=true" bitwise.lua

This behaviour seems to be reproducible.

Versions:

YkLua - yk-location-allocation/056cf6ae7cb3ebd59a7e0dc89df99c03f0e8d3d9 Yk - master/a690e6eaf7253a4fa9c04bb54406c07b7efc0085

After https://github.com/ykjit/yk/pull/830 change in YK, we get new errors :)
