Ancestors: Kernel-ul.755

Remove Integer>>hex8. This is used only in VMMaker for printing hex representations of 32-bit values. It should be maintained as a VMMaker extension, along with whatever extension may be required for formatted printing of 64-bit values.

Add Time class>>primPosixMicrosecondClockWithOffset in addition to primUTCMicrosecondClock and primLocalMicrosecondClock. There are three microsecond primitives that are (or will be) supported on all Cog and interpreter VMs that may be accessed as:

{
        Time primUTCMicrosecondClock .
        Time primLocalMicrosecondClock .
        Time primPosixMicrosecondClockWithOffset
}

- ----- Method: Integer>>hex8 (in category 'printing') -----
- hex8
- "Print the receiver in base 16 with prefixed base, using at least 8 digits.
- DO NOT CHANGE THIS!!  The Cog VMMaker depends on this.
- Consider using storeStringBase: 16 length: 11 padded: true instead."
-  "16r3333 hex8"
- | hex |
- hex := self hex.  "16rNNN"
- ^hex size < 11

- ifFalse: [hex]!
