002 Building instruction and test of BishengJDK11 on HiFive Unleashed

Dingli Zhang, 2020.11.20

BishengJDK 11 now brings the template interpreter and backends of C1/C2 compiler to the RISC-V world. We supports RV64G (G used to be represent the IMAFD base and extensions of RISC-V ISA) with BV (bit-manipulation and vector extensions) on the way, and the compressed instructions are out of plan.

This test is to build the JDK on RISCV64 and start to do some benchmark on HiFive Unleashed.
