Fixed 6821700: tune VM flags for peak performance

Problem:
Tune C2 flags default values for peak performance.

Solution:
Change InlineSmallCode flag to platform specific and
change its default value to 1500 on sparc (ran refworkload
on N1, N2 and my station (US3), 32- and 64-bit VM).
Changing FreqInlineSize default value had negative
effects so I did not change it.

Do not inline StringCache::profile() when strings caching
is used since it runs only during an application startup.

Fix verified (y/n): y, refworkload
