[COMMITTED 029/141] gccrs: Remove query mode on CompileItem

[arthur.cohen@embecosm.com]

From: Pierre-Emmanuel Patry <pierre-emmanuel.patry@embecosm.com>

Query mode was a hack to catch up some compile errors early, it was
deemed to be removed at some time. Recent changes to NR1 highlighted
an incompatibility with it hence it's removal.

gcc/rust/ChangeLog:

	* backend/rust-compile-item.h: Remove query mode.
	* backend/rust-compile-resolve-path.cc (HIRCompileBase::query_compile):
	Likewise.
