f723147f04 Streamlined clock rate handling. 
* Docs say that CLK_TCK is an obsolete alias of CLOCKS_PER_SEC so there's no point in individual definitions.
* All targets determining the clock rate at runtime can use a common handling.

2fcd8b934a Made HGR segment obligatory. 
Requiring the HGR segment makes the configs a little less flexible, but for the intended use case the HGR segment actually is necessary. And as we learned now, making the HGR segment obligatory helps users to not shoot themselves in the foot.

5c43d1e04f Changed codegen for postfix inc/dec operations by deferring them till sequence points. 
This usually allows faster & smaller code.
Note that deferred operations must still be called at sequence points even if the whole expressions containing them had constant values.

cbm_load() is needed because the Pet/CBM Kernals don't have a LOAD function that can be used by machine code programs.

81550ca1ee CS_MergeLabels: Keep labels referenced by data 
Partial fix for ICE in #1211.  This may fix enough to allow #1049 to be
fixed.

When merging labels, keep the first label with a ref that has no JumpTo;
this is a data segment label, used by computed gotos.

The real fix is to track and rewrite labels in data, but this is more
involved.

fd208fdf0b - Added support for calling subdir Makefiles for the make targets 'samples' and 'clean'. 
- Adjusted the 'tutorial' Makefile to actually work as expected.

Note: The 'disasm' and 'geos' Makefiles don't seem to work so they are not called as of now.

b931e65811 Fix ICE for bit-fields with typedef 
Fixes #1267

Avoid ICE, but treat plain int bit-fields declared via typedef as
signed rather than unsigned.  It is more efficient to treat them
as unsigned, but this requires distinguishing int from signed int,
and this is curently not done.

d0089aef95 Fix bit-field truncation warning message 
Fix copy & paste bug with warning message.

struct X {
      signed int a : 3;

struct X g = { 5 };

Before:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to 5

After:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to -3
