tree-optimization/107898 - ICE with -Walloca-larger-than

The following avoids ICEing with a mismatched prototype for alloca
and -Walloca-larger-than using irange for checks which doesn't
like mismatched types.

PR tree-optimization/107898
* gimple-ssa-warn-alloca.cc (alloca_call_type): Check
the type of the alloca argument is compatible with size_t
before querying ranges.

(cherry picked from commit 9948daa4fd0f0ea0a9d56c2fefe1bca478554d27)
