Log Message:
-----------
Clean up and improve documentation of x86_64 registers (#1630)
* Improve comments for register lengths
* Separate MMX/3DNow! and x87 register lengths and categories
The MMX* registers are only the lower 64 bits of the st* ones.
* Fix x86_64 subrange mappings in MachRegister::getROSERegister
The values in the two namespaces are not the same.
* Improve comments for EFLAGS fields
* Use symbolic names for the segment register base IDs
* Add missing flag1 from RFLAGS
* Add missing flag3 from RFLAGS
* Add missing flag5 from RFLAGS
* Add missing flagc from RFLAGS
FLAGC is the lower bit of the I/O Permission Level field.
* Add missing flagd from RFLAGS
FLAGC is the upper bit of the I/O Permission Level field.
* Add missing flagf from RFLAGS
* Add missing Virtual-8086 mode (VM) rFLAGS field
* Add conversion to ROSE register for Resume Flag
* Add conversion to ROSE register for Nested Task flag
* Add missing Alignment Check/Access Control (AC) RFLAGS field
* Add missing Virtual Interrupt Flag (VIF) RFLAGS field
* Add missing Virtual Interrupt Pending (VIP) RFLAGS field
* Add missing ID Flag (ID) RFLAGS field
* Fix avx-512 opmask size.
It's 64 bits, not 128.
From Intel(R) 64 and IA-32 Architectures Software Developer’s Manual
June 2021
15.6.1 OPMASK Register to Predicate Vector Data Processing
The opmask is a set of eight architectural registers of size
MAX_KL (64-bit).
* Rename OCT to XMMS
This makes it consistent with the names used for the other vector
extensions.
* Add missing subranges in MachRegister::getROSERegister
* Preserve register number in getBaseRegister
* Clear whole subrange byte for GPRs in getBaseRegister
