Samuel Pitoiset 2c2aaf275c ac/llvm: force fneg/fabs to flush denorms to zero if requested 
LLVM optimizes these instructions with XOR/AND and it loses
the sign bit.

Samuel Pitoiset 7dfb15fff1 ac/llvm: add AC_FLOAT_MODE_ROUND_TO_ZERO 
Because some instructions will be optimized by the backend compiler,
the driver has to manually flush to zero to keep the result exact.

Timur Kristóf 3a08110d43 amd: Move all amd/common code that depends on LLVM to amd/llvm. 
This commit is a step towards the goal of being able to build RADV
without LLVM. In the future we would like to offer the option to
use RADV solely with ACO. There is still a need for the common AMD
code located in amd/common but the LLVM specific parts need to be
separated.
