MdePkg: Remove X86 ASM and S files NASM has replaced ASM and S files. 1. Remove ASM from all modules. 2. Remove S files from the drivers only. 3. https://bugzilla.tianocore.org/show_bug.cgi?id=881 After NASM is updated, S files can be removed from Library.

MdePkg/BaseLib: Preserve EBX register and fix stack offset to LinearAddress in AsmFlushCacheLine() The value of EBX must be preserved to follow IA32 cdecl calling convention in the assembly implementation of AsmFlushCacheLine(). The CPUID instruction modifies the EBX register. The EBX register value is saved onto the stack before CPUID and restored from the stack after CPUID. The update to the inline assembly implementation of AsmFlushCacheLine() changed the location of the LinearAddress parameter value on the stack. The hardcoded lookup using [esp + 4] is not correct. Use the parameter name LinearAddress instead of the hard coded [esp + 4] stack location to prevent this issue from occurring again if there are changes to the inline assembly in the future.

1. Updated function headers in all assembly files. 2. Split x86LowLevel.c into a bunch of C files to make images linked with BaseLib smaller. 3. Fixed a few minor bugs. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@1066 6f19259b-4bc3-4df7-8a09-765794883524
