I meant to fold this into 47601815ec3a4f31c797c75748af08acfabc46dc
but failed to do so.

  [LoongArch] Remove AssemblerPredicate for features: f/d/lsx/lasx/lvz/lbt

Linux LoongArch port [1] uses `-msoft-float` (implies no FPU) in its
`cflags` while it also uses floating-point insns in asm sources [2].
GAS allows this usage while IAS currently does not.

This patch removes `AssemblerPredicate`s for floating-point insns so
that to make IAS compitable with GAS. Similarly, also remove
`AssemblerPredicate`s for other ISA extensions, i.e. lsx/las/lvz/lbt.

  [llvm-objcopy] Add LoongArch support

Apart from general feature parity, this is also necessary for enabling
ClangBuiltLinux that defaults to using LLVM tools.

While at it, add a missing comment for the Hexagon definition directly
above, so it doesn't get confused with the SPARC definitions.
