    BaseTools/GenFw: Add X64 GOTPCREL Support to GenFw
    
    Adds support for the following X64 ELF relocations to GenFw
      R_X86_64_GOTPCREL
      R_X86_64_GOTPCRELX
      R_X86_64_REX_GOTPCRELX
    
    Background:
    The GCC49 and GCC5 toolchains use the small pie model for X64.  In the
    small pie model, gcc emits a GOTPCREL relocation whenever C code takes
    the address of a global function.  The emission of GOTPCREL is mitigated
    by several factors
    1. In GCC49, all global symbols are declared hidden thereby eliminating
    the emission of GOTPCREL.
    2. In GCC5, LTO is used.  In LTO, the complier first creates intermediate
    representation (IR) files.  During the static link stage, the LTO compiler
    combines all IR files as a single compilation unit, using linker symbol
    assistance to generate code.  Any global symbols defined in the IR that
    are not referenced from outside the IR are converted to local symbols -
    thereby eliminating the emission of GOTPCREL for them.
    3. The linker (binutils ld) further transforms any GOTPCREL used with
    the movq opcode to a direct rip-relative relocation used with the leaq
    opcode.  This linker optimization can be disabled with the option
    -Wl,--no-relax.  Furthermore, gcc is able to emit GOTPCREL with other
    opcodes
      - pushq opcode for passing arguments to functions.
      - addq/subq opcodes for pointer arithmetic.
    These other opcode uses are not transformed by the linker.
    Ultimately, in GCC5 there are some emissions of GOTPCREL that survive
    all these mitigations - if C code takes the address of a global function
    defined in assembly code - and performs pointer arithmetic on the
    address - then the GOTPCREL remains in the final linker product.
    A GOTPCREL relocation today causes the build to stop since GenFw does
    not handle them.  It is possible to eliminate any remaining GOTPCREL
    emissions by manually declaring the global symbols causing them to have
    hidden visibility.  This patch is offered instead to allow GenFw to
    handle any residual GOTPCREL.
