Add ARM target for CoreCLR on Linux.

c_runtime/vprintf/test1 is disabled as casting NULL to va_list is
against the C specification.

Fix SetFilePointer tests on 32 bit platforms.

Define _FILE_OFFSET_BITS=64 so that we have long file support on 32 bit
platforms.

Implement context capture/restore for ARM.

Link libgcc_s before libunwind on ARM so C++ exceptions work.

Translate armasm to gas syntax.

Specify Thumb, VFPv3, ARMv7 for the ARM target.

Add ARM configuration to mscorlib build

Implement GetLogicalProcessorCacheSizeFromOS in PAL.

Set UNWIND_CONTEXT_IS_UCONTEXT_T from configure check.
