[PATCH 0/2] Add SSE4.1 "floor" intrinsics

[Paul A. Clarke]

Just like the "ceil" intrinsics,
Instead of copying some tests from gcc/testsuite/gcc.target/i386,
I created new tests.  The i386 tests in question used rand() to
generate the input data and assembly to compute the rounded values.
Using rand() for testing seems wrong, and the assembly is obviously
not portable.  I use static data, primarily exercising the edges of
dynamic ranges (where fractions start to be unrepresentable).

Patch 2/2, containing the test cases, depends on the infrastructure
added in the previous patches for "ceil".
