8288047: Accelerate Poly1305 on x86_64 using AVX512 instructions

8

Handcrafted x86_64 asm for Poly1305. Main optimization is to process 16 message blocks at a time. For more details, left a lot of comments in `macroAssembler_x86_poly.cpp`. - Added new KAT...

8320794: Emulate rest of vblendvp[sd] on ECore

3

Replace vpblendvp[sd] with macro assembler call and test in: - `C2_MacroAssembler::vector_cast_float_to_int_special_cases_avx` (insufficient registers for 1 of 2 blends) - `C2_MacroAssembler::vector_cast_double_to_int_special_cases_avx` - `C2_MacroAssembler::vector_count_leading_zeros_int_avx` Functional testing with existing and new tests: `make...
