2022-07-06common/x64: Use TSC clock rate from CPUID when availableMarshall Mohror1-0/+13
The current method used to estimate the TSC is fairly accurate - within a few kHz - but the exact value can be extracted from CPUID if available.
2022-04-23general: Convert source file copyright comments over to SPDXMorph1-2/+3
This formats all copyright comments according to SPDX formatting guidelines. Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

2022-03-11cpu_detect: Add additional x86 flags and telemetryWunkolo1-8/+22
Adds detection of additional CPU flags to cpu_detect and additions to telemetry output. This is not exhaustive but guided by features that [dynarmic utilizes](https://github.com/merryhime/dynarmic/blob/bcfe377aaa5138af740e90af5be7a7dff7b62a52/src/dynarmic/backend/x64/host_feature.h#L12-L33) as well as features that are currently utilized but not reported to telemetry(invariant_tsc). This is intended to guide future optimizations. AVX512 in particular is broken up into its individual subsets and some other processor features such as [sha](https://en.wikipedia.org/wiki/Intel_SHA_extensions) and [gfni](https://en.wikipedia.org/wiki/AVX-512#GFNI) are added to have some forward-facing data-points. What used to be a single `CPU_Extension_x64_AVX512` telemetry field is also broken up into individual `CPU_Extension_x64_AVX512{F,VL,CD,...}` fields.
2022-03-10cpu_detect: Revert `__cpuid{ex}` array-type argumentWunkolo1-6/+6
Restores compatibility with MSVC's `__cpuid` intrinsic.

2022-03-09cpu_detect: Update array-types to `span` and `array`Wunkolo1-11/+13

2016-09-21Remove empty newlines in #include blocks.Emmanuel Gil Peyrot1-3/+1
This makes clang-format useful on those. Also add a bunch of forgotten transitive includes, which otherwise prevented compilation.
