RFR(XXS) 8187979 Clean up info printing at CDS dump time

[Jiangli Zhou]

Hi Ioi,

Thanks. The changes look good.

Since you are in the area, could you please also fix “[100% used … " in the dump output for the st* and oa* spaces. 

od  space:   6478224 [ 35.4% of total] out of   6479872 bytes [100.0% used] at 0x0000000800b12000
st0 space:    122880 [  0.7% of total] out of    122880 bytes [100% used] at 0x00000007ffc00000

Thanks,
Jiangli
