liblzma: Add a note why crc_always_inline exists for now.

Browse source 
Solaris Studio is a possible example (not tested) which
supports the always_inline attribute but might not get
detected by the common.h #ifdefs.

// If both __forceinline and inline are used, MSVC will issue a warning.
// Since MSVC's keyword is a replacement keyword, the lzma_always_inline
// macro must also contain the inline keyword when its not used in MSVC.
//
// NOTE: This doesn't use lzma_always_inline for now as support for it is
// detected using preprocessor macros which might miss a compiler that
// does support it. All compilers that support the CLMUL code support
// the attribute too; if not, we will hopefully get a bug report.
