[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).

[PowerPC] Support -mabi=ieeelongdouble and -mabi=ibmlongdouble gcc PowerPC supports 3 representations of long double: * -mlong-double-64 long double has the same representation of double but is mangled as `e`. In clang, this is the default on AIX, FreeBSD and Linux musl. * -mlong-double-128 2 possible 128-bit floating point representations: + -mabi=ibmlongdouble IBM extended double format. Mangled as `g` In clang, this is the default on Linux glibc. + -mabi=ieeelongdouble IEEE 754 quadruple-precision format. Mangled as `u9__ieee128` (`U10__float128` before gcc 8.2) This is currently unavailable. This patch adds -mabi=ibmlongdouble and -mabi=ieeelongdouble, and thus makes the IEEE 754 quadruple-precision long double available for languages supported by clang.
