Currently the MIPS code uses the old clock_get_ns() API to
calculate a time length in nanoseconds:
cpu->cp0_count_rate * clock_get_ns(MIPS_CPU(cpu)->clock)
This relies on the clock having a period which is an exact number
of nanoseconds.
Switch to the new clock_ticks_to_ns() function, which does the
multiplication internally at a higher precision.

The clock_get_ns() API claims to return the period of a clock in
nanoseconds. Unfortunately since it returns an integer and a
clock's period is represented in units of 2^-32 nanoseconds,
the result is often an approximation, and calculating a clock
expiry deadline by multiplying clock_get_ns() by a number-of-ticks
is unacceptably inaccurate.
Introduce a new API clock_ticks_to_ns() which returns the number
of nanoseconds it takes the clock to make a given number of ticks.
This function can do the complete calculation internally and
will thus give a more accurate result.

Out-of-range shifts have undefined results, but must not trap.
Mask off immediate shift counts to solve this problem.
This bug can be reproduced by running the following guest instructions:
xor %ecx,%ecx
sar %cl,%eax
cmovne %edi,%eax
After optimization, the tcg opcodes of the sar are
movi_i32 tmp3,$0xffffffffffffffff pref=all
sar_i32 tmp3,eax,tmp3 dead: 2 pref=all
mov_i32 cc_dst,eax sync: 0 dead: 1 pref=0xffc0300
mov_i32 cc_src,tmp3 sync: 0 dead: 0 1 pref=all
movi_i32 cc_op,$0x31 sync: 0 dead: 0 pref=all

0x200808d618: fffa5b9b illegal

In f47db80cc0, we handled odd-sized tail clearing for
the case of hosts that have vector operations, but did
not handle the case of hosts that do not have vector ops.
This was ok until e2e7168a21, which changed the encoding
of simd_desc such that the odd sizes are impossible.
Add memset as a tcg helper, and use that for all out-of-line
byte stores to vectors. This includes, but is not limited to,
the tail clearing operation in question.

The compiler encounters trace event format strings in generated code.
Format strings are error-prone and therefore clear compiler errors are
important.
Use the #line directive to show the trace-events filename and line
number in format string errors:
https://gcc.gnu.org/onlinedocs/gcc-10.2.0/cpp/Line-Control.html
For example, if the cpu_in trace event's %u is changed to %p the
following error is reported:
trace-events:29:18: error: format ‘%p’ expects argument of type ‘void *’, but argument 7 has type ‘unsigned int’ [-Werror=format=]
Line 29 in trace-events is where cpu_in is defined. This works for any
trace-events file in the QEMU source tree and the correct path is
displayed.
Unfortunately there does not seem to be a way to set the column, so "18"
is not the right character on that line.
