CMake: Make most target symbols hidden by default
Summary:
For builds with LLVM_BUILD_LLVM_DYLIB=ON and BUILD_SHARED_LIBS=OFF
this change makes all symbols in the target specific libraries hidden
by default.
A new macro called LLVM_EXTERNAL_VISIBILITY has been added to mark symbols in these
libraries public, which is mainly needed for the definitions of the
LLVMInitialize* functions.
This patch reduces the number of public symbols in libLLVM.so by about
25%. This should improve load times for the dynamic library and also
make abi checker tools, like abidiff require less memory when analyzing
libLLVM.so
One side-effect of this change is that for builds with
LLVM_BUILD_LLVM_DYLIB=ON and LLVM_LINK_LLVM_DYLIB=ON some unittests that
access symbols that are no longer public will need to be statically linked.
Before and after public symbol counts (using gcc 8.2.1, ld.bfd 2.31.1):
nm before/libLLVM-9svn.so | grep ' [A-Zuvw] ' | wc -l
36221
nm after/libLLVM-9svn.so | grep ' [A-Zuvw] ' | wc -l

[AArch64][SME] Add matrix register definitions and parsing support
SME introduces the ZA array, a new piece of architectural register state
consisting of a matrix of [SVLb x SVLb] bytes, where SVL is the
implementation defined Streaming SVE vector length and SVLb is the
number of 8-bit elements in a vector of SVL bits.
SME instructions consist of three types of matrix operands:
* Tiles: a ZA tile is a square, two-dimensional sub-array of elements
within the ZA array. These tiles make up the larger accumulator array
and the granularity varies based on the element size, i.e.
- ZAQ0..ZAQ15 (smallest tile granule)
- ZAD0..ZAD7
- ZAS0..ZAS3
- ZAH0..ZAH1
or ZAB0 (largest tile granule, single tile)
* Tile vectors: similar to regular tiles, but have an extra 'h' or 'v'
to tell how the vector at [reg+offset] is layed out in the tile,
horizontally or vertically. E.g. za1h.h or za15v.q, which corresponds
to vectors in registers ZAH1 and ZAQ15, respectively.
* Accumulator matrix: this is the entire accumulator array ZA.
This patch adds the register classes and related operands and parsing
for SME instructions operating on the accumulator array.
The ADDHA and ADDVA instructions which operate on tiles are also added
in this patch to make some use of the code added, later patches will
make use of the other operands introduced here.
