perf jevents: Add a new expression builtin strcmp_cpuid_str()
This will allow writing formulas that are conditional on a specific CPU type or CPU version. It calls through to the existing strcmp_cpuid_str() function in Perf which has a default weak version, and an arch specific version for x86 and arm64.
The function takes an 'ID' type value, which is a string. But in this case Arm CPU IDs are hex numbers prefixed with '0x'. metric.py assumes strings are only used by event names, and that they can't start with a number ('0'), so an additional change has to be made to the regex to convert hex numbers back to 'ID' types.

perf build: Disable fewer bison warnings
If bison is version 3.8.2, reduce the number of bison C warnings disabled. Earlier bison versions have all C warnings disabled. Avoid implicit declarations of yylex by adding the declaration in the C file. A header can't be included as a circular dependency would occur due to the lexer using the bison defined tokens.

perf expr: Make the evaluation of & and | logical and lazy
Currently the & and | operators are only used in metric thresholds like (from the tma_retiring metric):
tma_retiring > 0.7 | tma_heavy_operations > 0.1
Thresholds are always computed when present, but a lack of events may mean the threshold can't be computed. This happens with the option --metric-no-threshold for say the metric tma_retiring on Tigerlake model CPUs.
To fully compute the threshold tma_heavy_operations is needed and it needs the extra events of IDQ.MS_UOPS, UOPS_DECODED.DEC0, cpu/UOPS_DECODED.DEC0,cmask=1/ and IDQ.MITE_UOPS. So --metric-no-threshold is a useful option to reduce the number of events needed and potentially multiplexing of events.
Rather than just fail threshold computations like this, we may know a result from just the left or right-hand side. So, for tma_retiring if its value is "> 0.7" we know it is over the threshold. This allows the metric to have the threshold coloring, when possible, without all the counters being programmed.

This currently fails to parse as the left hand side if expression needs to be in parentheses. By allowing the if expression to have a right hand side that is an if expression we can parse the expression above, with left to right evaluation order that matches languages like Python.

perf expr: Add source_count for aggregating events
Events like uncore_imc/cas_count_read/ on Skylake open multiple events and then aggregate in the metric leader. To determine the average value per event the number of these events is needed. Add a source_count function that returns this value by counting the number of events with the given metric leader. For most events the value is 1 but for uncore_imc/cas_count_read/ it can yield values like 6.
Add a generic test, but manually tested with a test metric that uses the function.

perf metric: Modify resolution and recursion check
Modify resolution. Rather than resolving a list of metrics, resolve a metric immediately after it is added.
This simplifies knowing the root of the metric's tree so that IDs may be associated with it.
A bug in the current implementation is that all the IDs were placed on the first metric in a metric group.
Rather than maintain data on IDs' parents to detect cycles, maintain a list of visited metrics and detect cycles if the same metric is visited twice.
Only place the root metric onto the list of metrics.

perf metric: Don't compute unused events
For a metric like:
EVENT1 if #smt_on else EVENT2
currently EVENT1 and EVENT2 will be measured and then when the metric is reported EVENT1 or EVENT2 will be printed depending on the value from smt_on() during the expr parsing. Computing both events is unnecessary and can lead to multiplexing as discussed in this thread:
https://lore.kernel.org/lkml/20201110100346.2527031-1-irogers@google.com/
If the input is constant to certain operators like:
IDS1 if CONST else IDS2
then the result will be either IDS1 or IDS2 depending on CONST (which may be evaluated from an entire expression), and so IDS1 or IDS2 may be discarded avoiding events from being programmed.

When we're computing ID values, if we have constant values then compute the constant result. For example:

Later changes will use the constant values to hopefully eliminate ID values that don't need to be computed.
