fd55bcd060 R600/SI: Enable all tests that pass on VI without changes
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227214 91177308-0d34-0410-b5e6-96231b3b80d8

1f996fa36b R600/SI: Add a stub GCNTargetMachine
This is equivalent to the AMDGPUTargetMachine now, but it is the
starting point for separating R600 and GCN functionality into separate
targets.

It is recommened that users start using the gcn triple for GCN-based
GPUs, because using the r600 triple for these GPUs will be deprecated in
the future.

This matches the format produced by the AMD proprietary driver.

507636288f R600/SI: Change formatting of printed FP immediates
Only 1 decimal place should be printed for inline immediates.
Other constants should be hex constants.

Does not include f64 tests because folding those inline
immediates currently does not work.

f7a3c7e705 Fix interference caused by fmul 2, x -> fadd x, x
If an fmul was introduced by lowering, it wouldn't be folded
into a multiply by a constant since the earlier combine would
have replaced the fmul with the fadd.

18ecf3fff3 R600/SI: implement range reduction for sin/cos
These instructions can only take a limited input range, and return
the constant value 1 out of range. We should do range reduction to
be able to process arbitrary values. Use a FRACT instruction after
normalization to achieve this. Also add a test for constant folding
with the lowered code with unsafe-fp-math enabled.

v2: use DAG lowering instead of intrinsic, adapt test
v3: calculate constant, fold pattern into instruction definition
v4: misc style fixes, add sin-fold testcase, cosmetics
