This CL cleans up the setting of m_error. In most cases we don't need to
set m_error it will be set when we bubble up the nullptr return from the
various parse methods.
The m_error was set inconsitently previously and was confusing on if it
needed to be set or not.

This removes the need for them to have their own runner. Due to other
upstream changes some of the expectation files needed to be
updated. The suppressions have been updated to make sure the tests do
not run for non-XFA builds.
Having these tests run on the bots surfaced an MSAN issue in the XFA
code, which is fixed in this CL.

These are generally cheap enough to compute as needed, rather than
keeping around in memory all the time (plus the memory for the static
flag the compiler generates to check if initialized).

This CL simplifies the if expression parsing. The elseif construct has
been split into its own list of IfExpressions and no longer gets
stuffed into the elseExpression. A loop was added into the output methods
for the elseif expressions, which also means we can go from having:
if () {
} else {
if () {
} else {
}
}
to
if () {
} else if () {
} else {
}
Which is a bit nicer.

In all the places we call ParseBlockExpression we really mean to parse
an ExpressionList. Using ParseBlockExpression is confusing because the
formcalc grammar has a BlockExpression defined which corresponds to our
ParseDoExpression.
This CL converts the use of ParseBlockExpression into calls to
ParseExpressionList and then builds the BlockExpression class as needed.

The if token in formcalc is an internal keyword and can not be used as
an identifier. The current if parsing code will turn if into an
identifier if it fails to find the 'then' statement after the argument
list.
This should be a failed parse instead of coverting if to an identifier
and resetting the lexer.
