Be aware of overlapping global STG registers in CmmSink (#10521)
Summary:
On x86_64, commit e2f6bbd3a27685bc667655fdb093734cb565b4cf assigned
the STG registers F1 and D1 the same hardware register (xmm1), and
the same for the registers F2 and D2, etc. When mixing calls to
functions involving Float#s and Double#s, this can cause wrong Cmm
optimizations that assume the F1 and D1 registers are independent.
