i386: Enable TM MMX intrinsics with SSE2
hjl: This patch enables TM MMX intrinsics with SSE2 when MMX is disabled.

lto-plugin - support -save-temps, -v, --version
iains: This patch makes the lto-plugin follow the same approach to save-temps as collect2. -save-temps causes the temp file to be named meaningfully, and for the relevant input files to be saved in CWD. -v, —version causes the save actions to be output to stderr. one can get this to happen by just putting -save-temps, -v on the regular link line or (for compatibility with the way the -debug flag works) by appending -plugin-opt=-save-temps, etc. lto-plugin/ 2019-05-15 Iain Sandoe <iain@sandoe.co.uk> - lto-plugin.c (exec_lto_wrapper): Make the wrapper arguments filename more user-friendly.
