Merge #1154
1154: Add support for isize and usize type-hints r=philberty a=philberty This bug turned out to be that we expected a usize for the array capacity but the specified capacity turned out to be an integer inference variable which will default to a signed integer. The type resolution was missing handling the type-hints of isize and usize Fixes #1152 Co-authored-by: Philip Herron <philip.herron@embecosm.com>
