jyao1 3ba736f39c Revert incompatible change:
1) No API change from old version.
2) Change MACRO:
#define  MTRR_NUMBER_OF_VARIABLE_MTRR  32 // the semantics are changed from NUMBER to MAX_NUMBER.
#define  FIRMWARE_VARIABLE_MTRR_NUMBER  6 // wrong and deprecated
#define  MTRR_LIB_IA32_VARIABLE_MTRR_END 0x20F // wrong and deprecated
#define  RESERVED_FIRMWARE_VARIABLE_MTRR_NUMBER  2 // add new one.

jyao1 3b9be4164b Original MTRR lib hardcode VARIABLE_MTRR as 8. But it is 7 in Core2 if SMRR enabled, and 10 in latest Corei7.

jljusten d6d8e8925f BaseUefiCpuLib: Preserve EBX register in InitializeFloatingPointUnits
The EBX register should be preserved for the IA32 C calling convention.
The use of the CPUID instruction was modifying the EBX register, so
we push and pop EBX.
