[thumb,framelowering] Reset NoVRegs in Thumb1FrameLowering::emitPrologue.
Summary:
In this function, virtual registers can be introduced (for example
through calls to emitThumbRegPlusImmInReg). doScavengeFrameVirtualRegs
will replace those virtual registers with concrete registers later on
in PrologEpilogInserter, which sets NoVRegs again.
This patch fixes the Codegen/Thumb/segmented-stacks.ll test case which
failed with expensive checks.
