Sergei Trofimovich 0e6995a96b gnu-efi: fix lib/ia64/setjmp.S IA-64 build failure
The build failed as:
  lib/ia64/setjmp.S:171: Error: Unknown opcode `ldf.nt1 f26=[r10],8'
  lib/ia64/setjmp.S:178: Error: Operand 1 of `ldf.fill.nt1' should be a floating-point register

The change syncs longjmp definition with
    edk2/EdkCompatibilityPkg/Foundation/Library/EdkIIGlueLib/Library/BaseLib/Ipf/setjmp.s
pulling in:
- branch in the end of function
- registers used wrong instruction for float restore
