ArmPkg/Library/CompilerIntrinsicsLib: Enable VS2017/ARM builds Introduce CRT assembly replacements for __rt_sdiv, __rt_udiv, __rt_udiv64, __rt_sdiv64, __rt_srsh (by reusing the RVCT code) as well as memcpy and memset. For MSFT compatibility, some of the code needs to be explicitly forced to ARM, and the /oldit assembly flag needs to be added. Also, while RVCT_ASM_EXPORT macro invocations have been removed, the replacement code is designed to be as close as possible to the one that would have been generated if using the macros.

ArmPkg: Fix modsi3.S compilation across toolchains. modsi3.S references the symbol '__divsi3' by '___divsi3' which assumes the prefix is always required and supported.

ArmPkg/CompilerIntrinsicsLib: replace memcpy and memset with C code This replaces the various implementations of memset and memcpy, including the ARM RTABI ones (__aeabi_mem[set|clr]_[|4|8]) with a single C implementation for each. The ones we have are either not very sophisticated (ARM), or they are too sophisticated (memcpy() on AARCH64, which may perform unaligned accesses) or already coded in C (memset on AArch64). The Tianocore codebase mandates the explicit use of its SetMem() and CopyMem() equivalents, of which various implementations exist for use in different contexts (PEI, DXE). Few compiler generated references to these functions should remain, and so our implementations in this BASE library should be small and usable with the MMU off. So replace them with a simple C implementation that builds correctly on GCC/AARCH64, CLANG/AARCH64, GCC/ARM, CLANG/ARM and RVCT/ARM.

ArmPkg/CompilerIntrinsicsLib: switch to ASM_FUNC() asm macro Annotate functions with ASM_FUNC() so that they are emitted into separate sections.

ArmPkg/CompilerIntrinsicsLib: make the default memset() weak The ARM compiler intrinsics library defines __aeabi_memset() and memset() in the same object, which means that both will be pulled in if either is referenced. The IntrinsicLib in CryptoPkg defines its own, preferred memset(), which may clash with our memset(). So make our version weak.

ArmPkg: Rectify file modes Problems have been encountered because some of the source files have execute permission set. This can cause git to report them as changed when they are checked out onto a file system with inherited permissions. This has been seen using Cygwin, MinGW and PowerShell Git. This patch makes no change to source file content, and only aims to correct the file modes/permissions.

ArmPkg: use unified asm syntax for CLANG The CLANG assembler does not support the legacy, non-unified assembler syntax, i.e., it does not support the reordering of the condition suffixes with the increment/decrement before/after or byte/word suffixes, and it does not recognize the 'empty descending' (ED) suffix at all. So move to the unified syntax, and replace 'empty descending' with 'decrement after' or 'increment before' as appropriate.
