is switched of by about 0.8% (tested with int i<N>).

Additionally, this puts computing the diagnostic class into the hot
path more when parsing, in preparation for upcoming optimizations
in this area.

the option to print the runtime-specific description has been modified in the frame variable, memory read and expression command.

All three commands now support a --object-description option, with a shortcut of -O (uppercase letter o)

This is a breaking change:
frame variable used --objc as the long option name
expression used -o as a shortcut
memory read uses --objd as the long option name

Hopefully, most users won't be affected by the change since people tend to access "expression --object-description" under the alias "po" which still works

The test suite has been tweaked accordingly.

Don't warn about disabled macro expansion if we see the name of a function-like macro which isn't immediately followed by '('. FreeBSD's stdio.h #defines foo(x) to (foo)(x), apparently.

mention the inline memcpy / memset expansion code is a mess?

This patch split the ZeroOrLdSrc argument into two: IsMemset and ZeroMemset.
The first indicates whether it is expanding a memset or a memcpy / memmove.
The later is whether the memset is a memset of zero. It's totally possible
(likely even) that targets may want to do different things for memcpy and
memset of zero.

Also added more comments to explain why it is generally ok to return true.
- Rename getOptimalMemOpType argument IsZeroVal to ZeroOrLdSrc. It's meant to
be true for loaded source (memcpy) or zero constants (memset). The poor name
choice is probably some kind of legacy issue.
