Failures in dEQP using SwiftShader with LLVM 7.0 were caused by unsafe
floating point math optimizations, which are more aggressive than with
LLVM 3.0.

LLVM fails to resolve the __chkstck function for probing the stack when
it's larger than 4 kB. We don't need it for SwiftShader because newly
created threads have 1 MB of committed stack memory.

This commit removes `sw::Value`, `sw::BasicBlock`, and
`sw::SwitchCases`.  In LLVM 7.0, `llvm::Value`, `llvm::BasicBlock`, and
`llvm::SwitchCases` become final classes, thus we cannot derive from
those classes.  Fortunately, we don't have to derive from them.  We can
explicitly cast the pointers instead.

A texture's base level can be any positive integer, but SwiftShader
stores texture levels in a array that has an implementation
dependent size (IMPLEMENTATION_MAX_TEXTURE_LEVELS). To avoid
accessing this array out of bounds, a class was added to make sure
all accesses to the array are done within its bounds.

When a sampler object is bound to a texture unit, it overrides the
texture's filter modes. A texture without mipmaps can thus be complete
even if it has a filter mode which requires mipmaps, if there's a
sampler object with a filter mode which doesn't require mipmaps.

These host versions will be used by a future change to enable
the build of SwiftShader on the host, using Android extensions,
without needing to pull in non-host-ported parts of the Android
framework.

These headers are derived from the framework versions, but modified
slightly to minimize their dependency on other headers, and to reduce
code size. If a feature is introduced in the platform that SwiftShader
needs, it will need to be added to these headers (however, even if these
headers were copies, they would still need to be updated.)
