ArmPkg/ArmSoftFloatLib: switch to new version of softfloat library Update the INF description and the top level .c files in order to switch to the new version of the SoftFloat library imported as a Git submodule in the previous patch. Note that we no longer use the code that travelled a long way from the 2002 version of the softfloat library via NetBsd and the StdLib package. Instead, we are using the upstream version unmodified, with the glue .c file adopted from the OP-TEE project. This approach is much cleaner and much more maintainable. Note that support for the RVCT toolchains is being dropped at the same time. RVCT is mostly untested, and planned to be removed, and so it makes little sense to go to the trouble of upgrading this library for RVCT as well.

ArmPkg/ArmSoftFloatLib GCC4x: fix build failure The upstream SoftFloat code that was recently incorporated into ArmSoftFloatLib uses some parameterization to tweak the inlining and optimization behavior for different compilers. The custom platform.h file that sets these parameters is based on the upstream version for Linux/ARM, but was updated to include the 'always_inline' GCC attribute into the INLINE macro, to ensure that all definitions that are marked as inline are not only inlined into their callers, but also to ensure that no version of the function is ever emitted into the object file. This works fine on recent GCC and Clang, but the latter part turns out to break on GCC 4.x, resulting duplicate definition linker errors. Fortunately, the synticatically more appriopriate 'static inline' works fine on both the recent and the older compilers, so let's switch to that instead.
