Fix amd64 dwarf register number mapping (MMX register and higher)
Dwarf register numbers are defined in "System V Application Binary
Interface AMD64 Architecture Processor Supplement Draft Version 0.99.6"
The amd64_dwarf_regmap array is missing the 8 MMX registers in Figure
3.36: DWARF Register Number Mapping page 57. This leads to a wrong
value for the registers past this point.
gdb/ChangeLog:
Pushed by Joel Brobecker <brobecker@adacore.com>.
* amd64-tdep.c (amd64_dwarf_regmap array): Add missing MMX
registers.
Tested on x86_64-linux.
