RFR: 8014513: Sjavac doesn't detect 32-bit jvm properly

[Erik Joelsson]

Hello,

Here is a small patch fixing a problem with sjavac. Sjavac tries to be 
smart about sizing itself to no run out of memory. The logic for 
figuring out if it's running on a 32 or 64bit jvm is rather crude and 
misses on several platforms. This patch makes the code more robust.

Fixing this issue is a requirement to get sjavac to work well on all 
platforms in jprt.
