Revert "[GlobalISel][LLT] Introduce FPInfo for LLT (Enable bfloat, ppc128float and others in GlobalISel) (#155107)" (#188344)
This reverts commit b1aa6a45060bb9f89efded9e694503d6b4626a4a and commit
ce44d63e0d14039f1e8f68e6b7c4672457cabd4e.
This fails the build with some older gcc:
llvm/include/llvm/CodeGenTypes/LowLevelType.h:501:35: error: call to
non-constexpr function ‘static llvm::LLT llvm::LLT::integer(unsigned
int)’
return integer(getSizeInBits());
