Fix PR7193: if sibling call address can take a register, make sure there are enough registers available by counting inreg arguments. llvm-svn: 105092

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
