x86: rename .i assembler includes to .h .i is an ending used for preprocessed stuff. This patch therefore renames assembler include files to .h and guards the contents with an #ifdef __ASSEMBLY__.

x86, alternative: Add altinstruction_entry macro Add altinstruction_entry macro to generate .altinstructions section entries from assembly code. This should be less failure-prone than open-coding.
