Aaron Watry d6d0454231 math: Add ilogb ported from amd-builtins
The scalar float/double function bodies are a direct copy/paste
with usage of the CLC wrappers to vectorize them.

This commit also adds in the FP_ILOGB0 and FP_ILOGBNAN macros which are
equal to the results of ilogb(0.0f) and ilogb(float nan) respectively.

v2: Add FP_ILOGB0 and FP_ILOGBNAN definitions

Aaron Watry 8872800eff math: Add frexp ported from amd-builtins
The float implementation is almost a direct port from the amd-builtins,
but instead of just having a scalar and float4 implementation, it has
a scalar and arbitrary width vector implementation.

The double scalar is also a direct port from AMD's builtin release.

The double vector implementation copies the logic in the float vector
implementation using the values from the double scalar version.

Both have been tested in piglit using tests sent to that project's
mailing list.

Aaron Watry 23faa5a1f9 integer: remove explicit casts from _MIN definitions
The spec says (section 6.12.3, CL version 1.2):
  The macro names given in the following list must use the values
  specified. The values shall all be constant expressions suitable
  for use in #if preprocessing directives.

This commit addresses the second part of that statement.

Aaron Watry 43ee367d1e integer: Update integer limits to comply with spec
The values for the char/short/integer/long minimums were declared with
their actual values, not the definitions from the CL spec (v1.1).  As
a result, (-2147483648) was actually being treated as a long by the
compiler, not an int, which caused issues when trying to add/subtract
that value from a vector.

Update the definitions to use the values declared by the spec, and also
add explicit casts for the char/short/int minimums so that the compiler
actually treats them as shorts/chars. Without those casts, they
actually end up stored as integers, and the compiler may end up storing
the INT_MIN as a long.

The compiler can sign extend the values if it needs to convert the
char->short, short->int, or int->long

v2: Add explicit cast for INT_MIN and fix some type-o's and wrapping
    in the commit message.

Tom Stellard d9ca1f1596 configure: Add --enable-runtime-subnormal option
This makes it possible for runtime implementations to disable
subnormal handling at runtime.

When this flag is enabled, decisions about how to handle subnormals
in the library will be controlled by an external variable called
__CLC_SUBNORMAL_DISABLE.

Function implementations should use these new helpers for querying subnormal
support:
__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

In order for the library to link correctly with this feature,
users will be required to either:

1. Insert this variable into the module (if using the LLVM/Clang C++/C APIs).

2. Pass either subnormal_disable.bc or subnormal_use_default.bc to the
linker.  These files are distributed with liblclc and installed to
$(installdir).  e.g.:

llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_disable.bc

or

llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_use_default.bc

If you do not supply the --enable-runtime-subnormal then the library
behaves the same as it did before this commit.

In addition to these changes, the patch adds helper functions that
should be used when implementing library functions that need
special handling for denormals:

__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

The sincosD_piby4.h file is mostly the same as the builtin implementation
released by AMD. The inline attribute declaration is changed, and M_PI is
used instead of a constant double. Otherwise, the only difference is that
the header explicitly enables the fp64 pragma.
