e84d9e1fb3 runtime: do not split stacks in syscall status 
Split stack checks (morestack) corrupt g->sched,
but g->sched must be preserved consistent for GC/traceback.
The change implements runtime.notetsleepg function,
which does entersyscall/exitsyscall and is carefully arranged
to not call any split functions in between.

e87af8c43d misc/dashboard: don't update tip tag for release branch commits. 
This will mean that sub-repositories won't get built against the
release branch. They are often not compatible because the subrepos
often run ahead of the current release (e.g. go.tools is using
new additions to go/ast, and go.net is using new things in syscall)
so there's little point in checking them against cherrypick commits
when they'll be tested against those commits on tip anyway.

c44e483542 misc/notepadplus: use new User Defined Language system (UDL2) 
Add missing single quotation and backslash marks.

Change dot and underscore character keyword type.
"_" is a predeclared identifier, not a operator.
"." is a selector, x.f should be one identifier highlight.
So the fix is to change it.

Fixes #5775.
Fixes #5788.
Fixes #5798.

f8a850b250 runtime: refactor mallocgc 
Make it accept type, combine flags.
Several reasons for the change:
1. mallocgc and settype must be atomic wrt GC
2. settype is called from only one place now
3. it will help performance (eventually settype
functionality must be combined with markallocated)
4. flags are easier to read now (no mallocgc(sz, 0, 1, 0) anymore)
