Peter Collingbourne 628ec9f193 ELF: Place relro sections after non-relro sections in r/w segment.
This is in preparation for my next change, which will introduce a relro
nobits section. That requires that relro sections appear at the end of the
progbits part of the r/w segment so that the relro nobits section can appear
contiguously.

Because of the amount of churn required in the test suite, I'm making this
change separately.

Peter Smith 8646ced053 Initial support for ARM in lld.
Add support for an ARM Target and the initial set of relocations
    and PLT entries that are necessary for an ARM only hello world to
    link. This has been tested against an ARM only sysroot from the
    4.2.0 CodeSourcery Lite release.
    
    Tests have been added to test/ELF for the support that has been
    implemented.
    
    Main limitations:
    - No Thumb support
    - Relocations incomplete
    - No C++ exceptions support
    - No TLS support
    - No range extension or interworking veneer (thunk) support
    - No Build Attribute support
    - No Big-endian support
    
    The deprecated relocations R_ARM_PLT32 and R_ARM_PC24 have been
    implemented as these are used by the 4.2.0 CodeSourcery Lite release.
