Disable _tzcnt_u64 for ARM64EC 
The ARM64EC is a new Microsoft-designed ARM64 ABI that is compatible with AMD64 code. However, not all AMD64 intrinsic functions are supported. For, intrinsics that are lowered to AVX, AVX2 and AVX512 instructions are not supported, including the _tzcnt_u64. To make sure this file compiles for ARM64EC, the use of _tzcnt_u64 should be neutered.

meson: simplify version lookup and avoid deprecation warnings 
run_command() in development versions of meson will warn when the
`check: ` kwarg is not specified. At the same time, lz4 has some gnarly
code to manually check the return code and raise an error if it failed.

Kill two birds with one stone, by making run_command inherently raise a
fatal error when erroring out, then proceeding in the knowledge that it
must have succeeded.

Merge pull request #1040 from zeux/m1-fastdec 
Enable fast decoding on Apple/AArch64 builds (18-25% faster decompression)

22e232dada Enable fast decoding on Apple/AArch64 builds 
This makes decoding significantly faster on M1; measured on compressed source
code across 8 hardware threads, decompressing 294 MB to 1301 MB takes 513 ms
of cumulative work (2.53 GB/s) before, and 406 ms (3.2 GB/s) after this change
on M1 Pro.

There's no way to check if the target architecture is M1 specifically but the
gains are likely to be similar on recent iterations on Apple processors, and
the original performance issue was probably more specific to Qualcomm.

6f54156783 Remove ubuntu-16.04 as a test platform. 
The Ubuntu 16.04 environment is being removed by github
on September 20, 2021. They will induce 'brownouts'
starting from September 6 to get clients to move on.

This change removes testing of GCC versions prior to 4.8,
and clang versions prior to 3.9
