Subject: [PATCH] Unifdef unused scaler implementations

A number of "templated" scaler implementations are unused in the
implementation.  If any single one of them needs to be brought back
(unlikely), then it's a simple matter of removing an ifdef.

These templates turn off compilation of following scaler
implementations:

void Normal1x_9_8_L(const void*)
void Normal1x_9_8_R(const void*)
void Normal2x_9_8_L(const void*)
void Normal2x_9_8_R(const void*)
void Normal3x_9_8_L(const void*)
void Normal3x_9_8_R(const void*)
void NormalDw_9_8_L(const void*)
void NormalDw_9_8_R(const void*)
void NormalDh_9_8_L(const void*)
void NormalDh_9_8_R(const void*)
void HQ2x_15_L()
void HQ2x_15_R()
void HQ3x_15_L()
void HQ3x_15_R()
void Super2xSaI_15_L()
void Super2xSaI_15_R()
void SuperEagle_15_L()
void SuperEagle_15_R()
void _2xSaI_15_L()
void _2xSaI_15_R()
void AdvMame2x_15_L()
void AdvMame2x_15_R()
void AdvMame3x_15_L()
void AdvMame3x_15_R()
void Cache_9_8(const void*)
