Craig Topper	4802d4e23e	[X86] Don't use NOPL when the assembler is passed an empty CPU string. Update tests to force a CPU with NOPL Empty string should be equivalent to "generic" which doesn't allow NOPL. Force tests to use specificy 'pentiumpro' to guarantee NOPL.

[X86] Don't use NOPL when the assembler is passed an empty CPU string. Update tests to force a CPU with NOPL

Empty string should be equivalent to "generic" which doesn't allow NOPL. Force tests to use specificy 'pentiumpro' to guarantee NOPL.

Fixes PR35686

[MC] Write padding into fragments when -mc-relax-all flag is used

Summary:
When instruction bundling is enabled and the -mc-relax-all flag is
set, we can write bundle padding directly into fragments and avoid
creating large number of fragments significantly reducing LLVM MC
memory usage.

Test Plan: Regression test attached
