[X86][PPC] Support -mlong-double-64 -mlong-double-64 is supported on some ports of gcc (i386, x86_64, and ppc{32,64}). On many other targets, there will be an error: error: unrecognized command line option '-mlong-double-64' This patch makes the driver option -mlong-double-64 available for x86 and ppc. The CC1 option -mlong-double-64 is available on all targets for users to test on unsupported targets. LongDoubleSize is added as a VALUE_LANGOPT so that the option can be shared with -mlong-double-128 when we support it in clang. Also, make powerpc*-linux-musl default to use 64-bit long double. It is currently the only supported ABI on musl and is also how people configure powerpc*-linux-musl-gcc. Reviewed By: rnk Differential Revision: https://reviews.llvm.org/D64067 llvm-svn: 365412

[X86][PowerPC] Support -mlong-double-128 This patch makes the driver option -mlong-double-128 available for X86 and PowerPC. The CC1 option -mlong-double-128 is available on all targets for users to test on unsupported targets. On PowerPC, -mlong-double-128 uses the IBM extended double format because we don't support -mabi=ieeelongdouble yet (D64283).
