Andrew Trick b0dc18dd04 Fix an assert in exclusivity diagnostics when inouts escape.
An error found in DiagnoseInvalidEscapingCaptures can indicate invalid
SIL, which will cause DiagnoseStaticExclusivity to assert during SIL
verification. When the source-level closure captures an inout
argument, it appears in SIL to be a non-escaping closure. The SIL
verification then fails because the "nonescaping" closure actually
escapes.

Ensure that capture diagnostics run on closures before exclusivity
enforcement runs on the parent function. Bypass the SIL verification
assert if a diagnostic error was found.

Fixes rdar://75364904 (Crash with assertion `noescape partial_apply
has unexpected use`)
