This patch follows is a follow up to r178171, which uses the register form of call in preference to memory indirect on Atom. In this case, the patch applies the optimization to the code for reloading spilled registers. The patch also includes changes to sibcall.ll and movgs.ll, which were failing on the Atom buildbot after the first patch was applied. This patch by Sriram Murali. llvm-svn: 178193

Fix an inconsistency in the x86 backend that led it to reject "calll foo" on x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly named "callq", so this only impacted x86-32. This fixes rdar://8456370 - llvm-mc rejects 'calll' This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call, I will file a bugzilla. llvm-svn: 114534
