Merge #17527: Fix CPUID subleaf iteration
f93fc61c65d605eae2d3e2c98bdd30ae587fcdab Put bounds on the number of CPUID leaves explored (Pieter Wuille)
ba2c5fe1477cec80d7e02f824daba21a1021758e Fix CPUID subleaf iteration (Pieter Wuille)
Pull request description:
This fixes #17523.
The code to determine which CPUID subleaves to explore was incorrect in #17270. The new code here is based on Intel's reference documentation for CPUID (a document called "Intel® Processor Identification and the CPUID Instruction - Application Note 485", which I cannot actually find on their own website).
