Ilya Berezhniuk updated HARMONY-4940:
-------------------------------------

    Attachment: H-4940.diff

Attaching patch.

This patch removes runtime checking on IA-32 - there will be uncompressed mode only.
For 64-bit platforms there are 3 build modes selected by command-line option:

COMPRESSED_MODE=(compressed|uncompressed|switch)

for compressed only, uncompressed only, and runtime switchable modes correspondingly.

Default mode for 64-bit platforms is runtime-switchable, so as compression mode could be selected by the option -XX:vm.compress_references=(true|false)

Both 'build test' and EHWA suites are passed for me on IA-32/EM64t Linux
