Allow the use of an alternate symbol for calculating a function's size. The standard function epilog includes a .size directive, but ppc64 uses an alternate local symbol to tag the actual start of each function. Until recently, binutils accepted the .size directive as: .size test1, .Ltmp0-test1 however, using this directive with recent binutils will result in the error: .size expression for XXX does not evaluate to a constant so we must use the label which actually tags the start of the function. llvm-svn: 151200

[MC] Use .p2align instead of .align For historic reasons, the behavior of .align differs between targets. Fortunately, there are alternatives, .p2align and .balign, which make the interpretation of the parameter explicit, and which behave consistently across targets. This patch teaches MC to use .p2align instead of .align, so that people reading code for multiple architectures don't have to remember which way each platform does its .align directive.

Use the generic Lfunc_begin label on ppc. This removes yet another custom label to mark the start of a function. llvm-svn: 231390
