OK. Do you expect that calling TruncateDoubleToI from C is going to be common 
in TF and therefore I would need to update the macro to support csp as a stack 
or is it reserved to tests in which case I could update code-generator-arm64.cc 
to temporarily swap stack pointer?

Rodolph: We have to disable
cctest/test-run-machops/RunTruncateFloat64ToInt32P
on ARM64. Please take a look into fixing that issue (calling DoubleToIStub
from
machine code not inside JS function).
