target/i386: Remove unused XMMReg, YMMReg types and CPUState fields
In commitb7711471f5
in 2014 we refactored the handling of the x86 vector registers so that instead of separate structs XMMReg, YMMReg and ZMMReg for representing the 16-byte, 32-byte and 64-byte width vector registers and multiple fields in the CPU state, we have a single type (XMMReg, later renamed to ZMMReg) and a single struct field (xmm_regs). However, in 2017 in commitc97d6d2cdf
some of the old struct types and CPU state fields got added back, when we merged in the hvf support (which had developed in a separate fork that had presumably not had the refactoring ofb7711471f5
), as part of code handling xsave. Commitf585195ec0
then almost immediately dropped that xsave code again in favour of sharing the xsave handling with KVM, but forgot to remove the now unused CPU state fields and struct types. Delete the unused types and CPUState fields.
