4ede58e44b compiler: reduce calls to TypedTreeHasher
We need to check if our inference reached a fixed point. This is checked
using hash of the types in the AST, which is very slow. This patch
avoids computing the hash if we can make sure that the AST is definitely
changed, which is when we parse a new function.

For some simple programs with many functions, this can significantly
reduce the compile time by up to ~30%.

129cf8c1dd Phaser: Make set_nco_phase set the phase of the NCO
Previous to this commit `set_nco_phase()` set the phase of the DUC instead
of the NCO. Setting the phase of the NCO may be desirable to utilise the
auto-sync functionality of the double-buffered DAC-NCO settings.

f97baa8aec phaser: workaround malformed output with mixer_ena=1 & nco_ena=0
When Phaser is powered on and `init()` is first called, enabling the
DAC-mixer while leaving the NCO disabled causes malformed output.
This commit implements a workaround by making sure the NCO is enabled,
before being set to the disired state.

This commit also avoids the following procedure, resulting in
malformed output:
1. Operate Phaser with the DAC Mixer and NCO enabled
2. Set the NCO to a non-zero frequency
3. Disable the NCO in the device_db
4. Re-initialise Phaser

After this procedure, with CMIX disabled, incorrect output is produced.
To clear the fault one must re-enable the NCO and write the NCO freqeuncy
to zero before disabling the NCO.

The CMIX bits are bits 12-15 in register 0x0d. This has been checked
against the datasheet and verified on hardware. Until now, the bit for
CMIX1 was written to CMIX0. The CMIX0 bit was written to a reserved bit.

4f812cc4ed Phaser: zero oscillator amplitude after init() (close #1651)
Currently, `init()` leaves a single oscillator at full scale. The phase
accumulator of this oscillator is held continuously cleared. Provided no
upconverting mechanism is active (DUC, CMIX, NCO), this produces a full-scale
DC voltage. The DC voltage is blocked by hardware capacitors. This behaviour
is not mentioned by the `init` documentation.

If one attempts to use any other oscillator without reducing the amplitude
of the oscillator enabled by `init`, there is by significant clipping.

In the case that the NCO or CMIX are configured via the device_db
(suggested in the docs), leaving the osillator at full scale results in
full RF output power after calling `init()`. This may plausibly damage loads
driven by phaser.

407fba232d Phaser upconverter: set phase-frequency detector to 62.5 MHz (close #1648)
The suitable PFD clock depends on the use case and will likely need
to be configured by some users. All things being equal, a higher PFD
clock is desirable as is results in lower local oscillator phase-noise.

Phaser was designed around a maximum PFD clock of 62.5 MHz. In integer mode,
with no local oscillator frequency divisor set, a 62.5 MHz PFD clock results
in a 125 MHz local oscillator step size. Given the +-200 MHz range of the DUC
(more if using the DAC mixer), this step size will be acceptable to many.
This seems like the most appropreate default configuration as it should offer
the best phase-noise performance.

75445fe5f0 Phaser: expose and automate clearing of DAC sif_sync (close #1630 and #1650)
`sif_sync` must be triggered to apply NCO frequency changes. To achieve per
channel frequency tunability exeeding the range of the DUC, the NCO frequeny must
adjusted. User code will need to trigger `sif_sync` to achieve this.

`sif_sync` can only be triggered if the bit was cleared. To avoid this pitfall,
the clearing of `sif_sync` is automated.
