Inline CycleClock code and remove branch for x86 CycleClockSource function
This CL removes the relaxed load for x86 as there is no acquire price to pay on x86. It inlines the UnscaledCycleClock::Now() which is a single RTDSC op for x86, and likewise inlines CycleClock::Now() for x86. The inlining should mostly have secondary benefits such as reducing spills on outlined calls.
LTO may eventually hoist these functions inline for the hotspots, but it doesn't hurt to default inline this for all builds and let the compiler decide on the first pass.
The perlab benchmark is noisy for the plain BM_Now, but the other benchmarks and the run on my local machine are clear.
------------- Local Benchy Benchmark
name old cpu/op new cpu/op delta
BM_Now 3.41ns ± 1% 2.30ns ± 2% -32.52% (p=0.000 n=50+50)

Style, comment, and test updates
* Remove a redundant assert in uniform_real_distribution.
* Update comment in internal/generate_real.h
* Style updates to uniform_real_distribution_test
mainly replacing TypeParam with real_type, using aliases for some limits, etc.
* Add a few more minor tests.

Optimize CordReader logic now that CONCAT is removed
This CL cleans up various helper functions and logic remaining from previous complex CONCAT logic that is no longer needed, simplifying the CordReader logic.
