118 Fixes two bugs: 1) in the early branching code within the instruction decoder.
This prevented the early branching from working when built with Xilinx's tools,
while the code worked with Verilator. 2) The CPU was not working with the
traditional cache and early branching disabled. These two bugs masked each
other. The replacement code is simpler.

117 Bug fixes: This adds the zip_ucc() instruction as a builtin, fixes the zip_cc()
builtin (both are now unspec_volatile) together with fixing the *_context(int*)
builtins so that they use five registers, never four. Further, this fixes the
negative stack space offset bug. Many of the GCC files now have Zip debugging
hooks within them as well, to simplify further debugging of the compiler.

116 Updated binutils. This fixes problems with linking global variables, fixes
the map file report, adjusts the LJMP instruction disassembly to display the
resulting address, as well as in general fixing up link problems when
sizeof(byte) is 32-bits.
dgisselq 2319d 01h /zipcpu/
115 A bug fix, applies to when there are more than 9 interrupt lines into the CPU. dgisselq 2319d 01h /zipcpu/
114 Fixes a bug that killed make binutils before the build-gas directory
was created.
dgisselq 2324d 02h /zipcpu/
113 Bug fix: the Makefile wasn't building gcc, and the binutils would not allocate
space for common variables or zero'd (bss) variables properly. Several binutils
bugs were fixed to get variables to be allocated properly. Those are
reflected in this updated patch.

112 Removed some debugging code from the compiler. dgisselq 2327d 01h /zipcpu/
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.
dgisselq 2327d 02h /zipcpu/
110 The makefile no longer requires (or supports) building the obsolete machine
code test file optest.
dgisselq 2327d 02h /zipcpu/
109 This file is now marked as obsolete. dgisselq 2327d 02h /zipcpu/
