7d9bb37174f9526639d5acaa87868a752ba7d956 Add -mcpu=power11 support.
This patch adds the power11 option to the -mcpu= and -mtune= switches.
This patch treats the power11 like a power10 in terms of costs and reassociation
width.
This patch issues a ".machine power11" to the assembly file if you use
-mcpu=power11.
This patch defines _ARCH_PWR11 if the user uses -mcpu=power11.
This patch allows GCC to be configured with the --with-cpu=power11 and
--with-tune=power11 options.
This patch passes -mpwr11 to the assembler if the user uses -mcpu=power11.
This patch adds support for using "power11" in the __builtin_cpu_is built-in
function.
