> Attached is implementation of register-based calling convention (DRLFast) for DRLVM/Jitrino
on IA-32.
> By default, the new convention is off and the old good calling convention is used for
managed code.
> To turn the DRLFast on, the new switch is introduced: 'java -Xcc:drlfast'  (only meaningful
on IA-32).
> Please refer to 'java -X' online help for more details and for DRLFast tuning options.
> Please note: DRLFast is not yet supported in Jitrino.JET, will come up later.
> Comments and suggestions are welcome.
> For easier reviewing, the patch is cut by te modules affected.
> Tested with 'build test' and it passed on Win2003 and SuSE9/ia32.
