ArmPkg: factor out softfloat support from StdLib/LibC/SoftFloat In order to support software floating point in the context of DXE drivers etc, this factors out the core ARM softfloat support into a separate library.

ArmPkg/ArmSoftfloatLib: add missing entry points for RVCT The RVCT compiler may emit calls to the various __aeabi_c?cmp?? functions, which return their results via the CPU condition flags C and Z. According to ARM doc IHI 0043D 'Run-time ABI for the ARM architecture': The 3-way comparison functions c*cmple, c*cmpeq and c*rcmple return their results in the CPSR Z and C flags. C is clear only if the operands are ordered and the first operand is less than the second. Z is set only when the operands are ordered and equal. Add implementations for the double and float variants of the above.

ArmPkg/ArmSoftFloatLib: disable LTO build for GCC Building ArmSoftFloatLib with LTO results in errors like .../bin/ld: softfloat.obj: plugin needed to handle lto object .../bin/ld: __aeabi_dcmpge.obj: plugin needed to handle lto object .../bin/ld: __aeabi_dcmplt.obj: plugin needed to handle lto object .../bin/ld: internal error ../../ld/ldlang.c 6299 This library is only linked by OpensslLib at the moment, and only marginally used at runtime, so just disable LTO for it.

ArmPkg/ArmSoftfloatLib: restrict -fno-tree-vrp option to GCC46 and GCC47 The -fno-tree-vrp option is not required for GCC 4.8 or later, and is not supported by CLANG. So restrict its use to GCC 4.6 and 4.7, which are the oldest versions we support for ARM.

ArmPkg/ArmSoftFloatLib: add support for RVCT The ARM softfloat library in ArmSoftfloatLib currently does not build under RVCT, simply because the code includes system header files that RVCT does not provide. However, nothing exported by those include files is actually used by the library when built in SOFTFLOAT_FOR_GCC mode, so we can just drop all of them.
