fix PR8642: if a critical edge has a PHI value that can trap,
...
isel is *required* to split the edge. PHI values get evaluated
on the edge, not in their predecessor block.

Improved our argument parsing abilities to be able to handle stuff more like
...
a shell would interpret it. A few examples that we now handle correctly
INPUT: "Hello "world
OUTPUT: "Hello World"
INPUT: "Hello "' World'
OUTPUT: "Hello World"
INPUT: Hello" World"
OUTPUT: "Hello World"
This broke the setting of dictionary values for the "settings set" command
for things like:
(lldb) settings set target.process.env-vars ["MY_ENV_VAR"]=YES
since we would drop the quotes. I fixed the user settings controller to use
a regular expression so it can accept any of the following inputs for
dictionary setting:
settings set target.process.env-vars ["MY_ENV_VAR"]=YES
settings set target.process.env-vars [MY_ENV_VAR]=YES
settings set target.process.env-vars MY_ENV_VAR=YES
We might want to eventually drop the first two syntaxes, but I won't make
that decision right now.
This allows more natural setting of the envirorment variables:
settings set target.process.env-vars MY_ENV_VAR=YES ABC=DEF CWD=/tmp

which have trapping constant exprs in them due to PHI nodes.
Eliminating them can cause the constant expr to be evalutated

There is a test case, but unfortunately it's sensitive to random code changes.
