[dpanfilyonok]

Proposed Changes

Added:

• Bitwise XOR, Bitwise Negation
• Support of non-integer for loops and loops with step (fix #114)
• Support of more types of barriers (barrierLocal, barrierGlobal, barrierFull)
• Support of structs transferring
• Support of using DU inside kernels
• Support of using atomic inc and dec for all suitable types
• Way to specify exact path to OpenCL.dll using BRAHMA_OCL_PATH env variable (fix #124, fix #123) (should be tested)

Also

• Improved data transferring to unmanaged memory. Now, in parallel
• Simplified types translation
