intel_alm: direct LUTRAM cell instantiation
By instantiating the LUTRAM cell directly, we avoid a trip through
altsyncram, which speeds up Quartus synthesis time. This also gives
a little more flexibility, as Yosys can build RAMs out of individual
32x1 LUTRAM cells.
While working on this, I discovered that the mem_init0 parameter of
<family>_mlab_cell gets ignored by Quartus.

kernel: Trap in `log_error()` when a debugger is attached
whitequark [Fri, 24 Apr 2020 19:37:47 +0000 (19:37 +0000)]
kernel: Trap in `log_error()` when a debugger is attached.
The workflow of debugging fatal pass errors in Yosys is flawed in
three ways:
1. Running Yosys under a debugger is sufficient for the debugger
to catch some fatal errors (segfaults, aborts, STL exceptions)
but not others (`log_error()`, `log_cmd_error()`). This is
neither obvious nor easy to remember.
2. To catch Yosys-specific fatal errors, it is necessary to set
a breakpoint at `logv_error_with_prefix()`, or at least,
`logv_error()`. This is neither obvious nor easy to remember,
and GDB's autocomplete takes many seconds to suggest function
names due to the large amount of symbols in Yosys.
3. If a breakpoint is not set and Yosys encounters with such
a fatal error, the process terminates. When debugging a crash
that takes a long time to reproduce (or a nondeterministic crash)
this can waste a significant amount of time.
To solve this problem, add a macro `YS_DEBUGTRAP` that acts as a hard
breakpoint (if available), and a macro `YS_DEBUGTRAP_IF_DEBUGGING`
that acts as a hard breakpoint only if debugger is present.
Then, use `YS_DEBUGTRAP_IF_DEBUGGING` in `logv_error_with_prefix()`
to obviate the need for a breakpoint on nearly every platform.
