math routine implementation with .s files

[Vladimir Ivanov]

Looks good!

As a side note, number of files added per operation looks like an 
overkill. What do you think about having a single .s file per operation?

   src/hotspot/os_cpu/linux_x86/svml_d_acos2_core_exha.s
   src/hotspot/os_cpu/linux_x86/svml_d_acos2_core_l9ha.s
   src/hotspot/os_cpu/linux_x86/svml_d_acos4_core_l9ha.s
   src/hotspot/os_cpu/linux_x86/svml_d_acos8_core_z0ha.s
   src/hotspot/os_cpu/linux_x86/svml_d_acos_cout_exha.s
   src/hotspot/os_cpu/linux_x86/svml_d_acos_data_exha.s

Also, some comments about naming. Current convention is to have os/cpu 
info duplicated in file name as well (e.g., 
src/hotspot/os_cpu/linux_x86/linux_x86_64.s or assembler_linux_x86.cpp). 
And I'd prefer the names clearly state their relation to Vector API 
(either in the file name or placed in a subdir).

(But that's not something requiring immediate attention.)

Best regards,
Vladimir Ivanov
