4a6a3aff5d em: add macro to force gcc to obey inline keyword 
History: when the emulator was first developed on OSX 10.4 (PowerPC),
the inline keyword was added by profiling with Apple's pretty
fantastic Shark profiler.  Apple's version of gcc had an -fobey-inline
switch that the makefile used to force gcc to obey the inline keyword.
This macro does the same thing

9054d69446 em.c, etc: use gv.xxx instead of gvp->xxx for 13% speed increase, from 
37.5 Prime MIPS on Linode VM to 42.5 MIPS.  gvp-> was faster on the
PowerPC architecture when gvp was kept in a dedicated register, but
that does not apply to Intel.

Old:

Timing CPU,  20.0 ticks per second...
  35.3 Prime MIPS for 16-bit ADD loop
  40.0 Prime MIPS for 16-bit MPY loop
  42.1 Prime MIPS for 16-bit DIV loop
  21.4 Prime MIPS for 32-bit ADD loop
  30.8 Prime MIPS for 32-bit MPY loop
  28.6 Prime MIPS for 32-bit DIV loop
  57.1 Prime MIPS for 16-bit X=0 loop
  44.4 Prime MIPS for 32-bit X=0 loop
  37.5 average Prime MIPS

New:

dc24f26eb1 Use registers on PPC for demo/production build, don't install sigquit, 
don't use async I/O for PNC.  Signals don't work with registers enabled.

83e05663cb - Replace HOBBY #ifdef with DEMO, 
- Remove long integers so x86_64, where long is 8 bytes, is like i686
compile, where long is 4 bytes.
- Dont' handle xon/xoff on sys console in full duplex
- Add geom hash for DEMO emulator
- Add -mmacosx-version-min=10.4 option for DEMO emulator
- Add 1-line AMLC and 2-node PNC to DEMO emulator

7b2ea3828b Don't print memory contents on a fatal error. Diag CPU.TIMER causes a 
fatal error in get16trap, and printing the memory contents causes a
nested fatal error.

88d7a3fba6 Add a way for device to be polled when CPU is idle. Maybe this can be used 
to interleave user processes with device & DIM processes, for example, during
a file upload.
